-
The LOG statement sends the quoted message to the log file or to the Log window of the SAS session at the client. Although it is unnecessary to include LOG statements in your script file, the LOG statements keep the user informed about the progress of the connection.
-
The IF/THEN statement can detect whether the script was called by the SIGNON statement or the SIGNOFF statement. When you are signing off, the IF/THEN statement directs script processing to the statement labeled SIGNOFF. See step 12.
-
The WAITFOR statement awaits the login prompt from the server. If the statement does not receive the prompt within 120 seconds, it directs script processing to branch to the statement labeled NOINIT.
-
The INPUT statement displays a window with the text Userid? to allow the user to enter a server logon user ID. The TYPE statement sends a line feed to the server to enter the user ID to the server.
-
The WAITFOR statement waits for the password prompt from the server and branches to the NOLOG label if it is not received within 30 seconds. The INPUT statement that follows the WAITFOR statement displays a window in which the user enters a password.
-
The WAITFOR statement waits for one of several common UNIX prompts and branches to various error handles if a prompt is not displayed. For a connection to the UNIX spawner, the string "Hello >" is received and the control branches to the unxspawn label in step 10. Verify that the WAITFOR statement in the script looks for the correct prompt for your site.
-
The TYPE statement invokes SAS on the server. The -DMR option is necessary to invoke a special processing mode for SAS/CONNECT. The -COMAMID option specifies the access method that is used to make the connection.
-
The message SESSION ESTABLISHED is displayed when a SAS session is started on the server by using the options -DMR and -COMAMID TCP. The WAITFOR statement awaits the display of the message SESSION ESTABLISHED to be issued by the server. If the SESSION ESTABLISHED response is received within 90 seconds, processing continues with the next LOG statement. If the SESSION ESTABLISHED response does not occur within 90 seconds, the script assumes that the remote SAS session has not started, and processing branches to the statement labeled NOSAS.
-
After the connection has been successfully established, the user must stop the rest of the script from processing. Without this STOP statement, processing continues through the remaining statements in the script.
-
This section of code is executed when you connect to a remote UNIX spawner.
-
The TYPE statement invokes SAS on the server. The -DMR option is necessary to invoke a special processing mode for SAS/CONNECT. The -COMAMID option specifies the access method that is used to make the connection.
-
This section of code is executed when the script is invoked to terminate the link. The IF statement (see step 2) sends processing to this section of the script when the script is invoked by a SIGNOFF statement. This section logs the user off the server after the user executes LOGOFF . Before it stops the link, the script issues a LOG statement to notify the user that the link is terminated.
-
These statements are processed only if the prompts expected in the previous steps are not received. This section of the script issues messages to the SAS log at the client and then abnormally ends the script processing as well as the SIGNON.
| TCPWIN.SCR Script |
The following script signs a client on and off a Windows server by using the TCP/IP access method.
/* trace on; */ /* echo on; */ /*-------------------------------------------------------------------*/ /*-- Copyright (C) 2007 by SAS Institute Inc., Cary NC --*/ /*-- --*/ /*-- name: tcpwin.scr --*/ /*-- --*/ /*-- purpose: SAS/CONNECT SIGNON/SIGNOFF script for connecting --*/ /*-- to a Windows host by --*/ /*-- using the TCP/IP access method. --*/ /*-- --*/ /*-- notes: 1. You must have the spawner program executing on --*/ /*-- the remote Windows workstation --*/ /*-- in order for the local session to be able to --*/ /*-- establish the connection. If the spawner is --*/ /*-- running on the remote node, you will receive a --*/ /*-- message that tells you that the connection has --*/ /*-- been refused. --*/ /*-- --*/ /*-- 2. You must have specified OPTIONS COMAMID=TCP --*/ /*-- in the local SAS session before using the SIGNON --*/ /*-- command. --*/ /*-- --*/ /*-- assumes: 1.

Starting remote SAS now.'; /* NOTERMINAL suppresses prompts from remote SAS session. */ /* NO$SYNTAXCHECK prevents remote side from going into syntax */ /* checking mode when a syntax error is encountered. */ 7 type 'sas -dmr -comamid tcp -device grlink -noterminal -no$syntaxcheck' LF; 8 waitfor 'SESSION ESTABLISHED', 120 seconds : nosas; 9 log 'NOTE: SAS/CONNECT conversation established.'; stop; /*---------------- TCP/IP SIGNOFF -----------------------------------*/ 10 signoff: log 'NOTE: SAS/CONNECT conversation terminated.'; stop; /*--------------- SUBROUTINES -----------------------------------*/ /*--------------- ERROR ROUTINES --------------------------------*/ 11 notcp: log 'ERROR: Incorrect communications access method.'; log 'NOTE: You must set "OPTIONS COMAMID=TCP;" before using this'; log ' script file.'; abort; noprompt: log 'ERROR: Did not receive userid prompt.'; log 'NOTE: Ensure spawner process is running on remote node.'; abort; nolog: log 'ERROR: Did not receive password prompt.'; abort; nouser: log 'ERROR: Unrecognized userid or password.'; abort; nosas: log 'ERROR: Did not get SAS software startup messages.'; abort; timeout: log 'ERROR: Timeout waiting for remote session response.'; abort;
-
The LOG statement sends the quoted message to the log file or to the Log window of the SAS session at the client. Although it is not necessary to include LOG statements in your script file, the LOG statements keep the user informed about the progress of the connection.
-
The IF/THEN statement detects whether the script was called by the SIGNON statement or by the SIGNOFF statement. When you sign off, the IF/THEN statement directs script processing to the statement that is labeled SIGNOFF. See step 10.
-
The WAITFOR statement awaits the login prompt from the server and branches to various error handles if the prompt is not displayed.
-
The INPUT statement displays a window with the text Userid? to allow the user to enter a server logon user ID. The TYPE statement sends a line feed to the server to enter the user ID to the server.
-
The WAITFOR statement awaits the password prompt from the server and branches to the NOLOG label if it is not received within 120 seconds. The INPUT statement that follows the WAITFOR statement displays a window in which the user enters a password.
-
The WAITFOR statement awaits the "Hello > " prompt that it expects to see from the Windows spawner. If the statement does not receive the prompt within 120 seconds, it directs script processing to branch to the statement that is labeled TIMEOUT.
-
The TYPE statement invokes SAS on the server. The -DMR option is necessary to invoke a special processing mode for SAS/CONNECT. The -COMAMID option specifies the access method that is used to make the connection.
-
The message SESSION ESTABLISHED is displayed when a SAS session is started on the server by using the -DMR and -COMAMID TCP options. The WAITFOR statement awaits the display of the message SESSION ESTABLISHED to be issued by the server. If the SESSION ESTABLISHED response is received within 120 seconds, processing continues with the next LOG statement. If the SESSION ESTABLISHED response does not occur within 120 seconds, the script assumes that the remote SAS session has not started and processing branches to the statement labeled NOSAS.
-
After the connection has been successfully established, the user must stop the rest of the script from processing. Without this STOP statement, processing continues through the remaining statements in the script.
-
This section of code is executed when the script is invoked to terminate the link. The IF statement (see step 2) sends processing to this section of the script when the script is invoked by a SIGNOFF statement. Before it stops the link, the script issues a LOG statement to notify the user that the link is terminated.
-
These statements are processed only if the prompts expected in the previous steps are not received. This section of the script issues messages to the SAS log at the client and then abnormally ends the script processing as well as the SIGNON.
| TCPMVS.SCR Script |
The following script enables a client to sign on and to sign off a z/OS server with TSO. The TCP/IP access method is used.

-
The LOG statement sends the quoted message to the log file or to the Log window of the SAS session at the client. Although it is not necessary to include LOG statements in your script file, the LOG statements keep the user informed about the progress of the connection.
-
The IF/THEN statement detects whether the script was called by the SIGNON statement. When you are signing off, the IF/THEN statement directs script processing to the statement labeled SIGNOFF. See step 10.
-
The WAITFOR statement awaits the login prompt from the server. If the statement does not receive the prompt within 120 seconds, it directs script processing to branch to the statement labeled NOINIT.
-
The INPUT statement displays a window with the text Userid? to allow the user to enter a server logon user ID. The TYPE statement sends a line feed to the server to enter the user ID to the server.
-
The WAITFOR statement waits for the password prompt from the server and branches to the NOLOG label if it is not received within 60 seconds. The INPUT statement that follows the WAITFOR statement displays a window for the user to enter a password.
-
The message SESSION ESTABLISHED is displayed when a SAS session is started on the server. The WAITFOR statement awaits the display of the message SESSION ESTABLISHED to be issued by the server. If the SESSION ESTABLISHED response is received within 120 seconds, processing continues with the next LOG statement. If the SESSION ESTABLISHED response does not occur within 120 seconds, the script assumes that the remote SAS session has not started and processing branches to the statement labeled NOTSO.
-
After the connection has been successfully established, the user must stop the rest of the script from processing. Without this STOP statement, processing continues through the remaining statements in the script.
-
This section prompts for a new password if the password has expired. The INPUT statement displays a window with the text New Password? to allow the user to enter a password. The TYPE statement sends a line feed to the server to enter the password to the server.

| TCPTSO9.SCR Script |
The following script enables a client to sign on and to sign off a z/OS server with TSO or to a z/OS spawner. The TCP/IP access method is used.
/* trace on; */ /* echo on; */ /*-------------------------------------------------------------------*/ /*-- Copyright (C) 2007 by SAS Institute Inc., Cary NC --*/ /*-- --*/ /*-- name: tcptso9.scr --*/ /*-- --*/ /*-- purpose: SAS/CONNECT SIGNON/SIGNOFF script for connecting --*/ /*-- to a z/OS host running SAS 9 or later via the --*/ /*-- TCP/IP access method. --*/ /*-- --*/ /*-- notes: 1.

-
The LOG statement sends the quoted message to the log file or to the Log window of the SAS session at the client. Although it is not necessary to include LOG statements in your script file, the LOG statements keep the user informed about the progress of the connection.
-
The IF/THEN statement detects whether the script was called by the SIGNON statement or by the SIGNOFF statement. When you sign off, the IF/THEN statement directs script processing to the statement that is labeled SIGNOFF. See step 18.
-
The WAITFOR statement awaits the login prompt from the server. If the statement does not receive the prompt within 120 seconds, it directs script processing to branch to the statement labeled NOINT.
-
The INPUT statement displays a window containing a prompt for a user ID so that the user can enter a server logon user ID. The TYPE statement sends a line feed to the server to enter the user ID to the server. This section is entered when the SAS/CONNECT spawner is encountered.
-
The WAITFOR statement waits for the password prompt from the server and branches to the SPNFAIL label if it is not received within 120 seconds. The INPUT statement that follows the WAITFOR statement displays a window for the user to enter a password in.
-
The WAITFOR statement awaits the "Hello>" prompt that it expects to receive from the spawner. If WAITFOR does not receive the prompt, it branches to various condition handlers.
-
The TYPE statement calls a shell script to start SAS, and it passes the options that are needed for the SAS/CONNECT session. For a sample shell script, see Defining the Shell Script for Starting SAS.
-
The message SESSION ESTABLISHED is displayed when a SAS session is started on the server by using the DMR and COMAMID=TCP options. The WAITFOR statement awaits the display of the message SESSION ESTABLISHED that is issued by the server. If the SESSION ESTABLISHED response is received within 120 seconds, processing continues with the next LOG statement. If the response is not received in the specified time period, the script assumes that the remote SAS session has not started and processing branches to the statement labeled SPNFAIL.
-
After the connection has been successfully established, the user must stop the rest of the script from processing. Without this STOP statement, processing continues through the remaining statements in the script. Prior to the STOP, a message is output to the log, which informs the user that the connection has been established.
-
This section prompts for a new password if the password has expired.
-
The INPUT statement displays a window that contains a prompt for a user ID so that the user can enter a server logon user ID. The TYPE statement sends a line feed to the server to enter the user ID to the server. This section is entered when a TSO login is encountered.
-
The WAITFOR statement awaits the password prompt from the server and branches to the NOLOG label if it is not received within 60 seconds. The INPUT statement that follows the WAITFOR statement displays a window for the user to enter a password.
-
The WAITFOR statement awaits the READY prompt after successful TSO logon. It branches to various condition handlers if the prompt is not received.
-
The TYPE statement issues the command to start SAS through the TSO session, and passes options that are needed for the SAS/CONNECT session.
-
The message SESSION ESTABLISHED is displayed when a SAS session is started on the server using the DMR and COMAMID=TCP options. The WAITFOR statement awaits the display of the message SESSION ESTABLISHED to be issued by the server. If the SESSION ESTABLISHED response is received within 120 seconds, processing continues with the next LOG statement. If the response is not received within the time limit, the script assumes that the remote SAS session has not started and processing branches to the statement labeled NOSAS.
-
After the connection has been successfully established, the user must stop the rest of the script from processing. Without this STOP statement, processing continues through the remaining statements in the script. Prior to the STOP, a message is output to the log, which informs the user that the connection has been established.
-
This section prompts for a new password if the password has expired.
-
This section of code is executed when the script to terminate the link is invoked. The IF statement (see step 2) sends processing to this section of the script when the script is invoked by a SIGNOFF statement. This section awaits a server prompt before displaying LOGOFF, which logs the user off the server. Before it terminates the link, the script issues a LOG statement to notify the user that the link is terminated.
Note: If the session has been established through the z/OS spawner, the WAITFOR and TYPE statements should be deleted or commented out. They are necessary only for signing off a TSO connection.
![[cautionend]](../../../../common/61991/HTML/default/images/cautend.gif)
-
This section handles the case where SIGNON reconnects the user to a SAS session that is still running on the server. It sends the script back to the section that starts SAS through a TSO sign-on.

These statements are processed only if the prompts expected in the previous steps are not received. This section of the script issues messages to the SAS log at the client and then abnormally ends the script processing as well as the SIGNON.
