Macro Facility under UNIX

Automatic Macro Variables in UNIX Environments

The following automatic macro variables are valid in all operating environments, but their values are determined by the operating environment:

SYSCC

contains the current SAS condition code. Upon exit, SAS translates this condition code to a return code that has a meaningful value for the operating environment.

Note: The value of SYSCC might not match the return code returned by the operating system. [cautionend]

Under UNIX, the following codes can be returned:

0	Normal completion
1	SAS issued warnings
2	SAS issued errors
3	ABORT;
4	ABORT RETURN n;
5	ABORT ABEND n;
6	Internal error

Note: When ERRORCHECK=NORMAL, the return code will be 0, even if an error exists in a LIBNAME or FILENAME statement, or in a LOCK statement in SAS/SHARE software. Also, the SAS job or session will not abort when the %INCLUDE statement fails due to a nonexistent file. For more information, see the ERRORCHECK= System Option in SAS Language Reference: Dictionary. [cautionend]

SYSDEVIC

contains the name of the current graphics device. The current graphics device is determined by the DEVICE system option. Contact your on-site SAS support personnel to determine which graphics devices are available at your site. (See DEVICE System Option: UNIX and SAS Language Reference: Dictionary for information about the DEVICE system option.)

SYSENV

reports whether SAS is running interactively. Values for SYSENV are FORE when the TERMINAL system option is in effect, and BACK when the NOTERMINAL system option is in effect.

SYSJOBID

lists the process identification number (PID) of the process that is executing SAS (for example, 00024).

SYSMAXLONG

returns the maximum long integer value allowed under UNIX, which is 9,007,199,254,740,992. On 32-bit systems, the maximum is 2,147,483,647.

SYSRC

holds the decimal value of the exit status code that is returned by the last UNIX command executed from your SAS session. The following output shows an interactive line mode SAS session that shows two sample SYSRC values:

Sample SYSRC Values

1? x 'data';
/bin/ksh: data: not found
2? %put UNIX exit status code is &sysrc;
UNIX exit status code is 256
3? x 'date';
Tue Mar 19 09:41:27 CST 2008
4? %put UNIX exit status code is now &sysrc;
UNIX exit status code is now 0

SYSSCP

returns the abbreviation for your operating environment, such as HP 800 , SUN 4 , or RS6000 .

SYSSCPL

returns the name of the specific UNIX environment that you are using, such as HP-UX , SunOS , or AIX . This variable returns the same value that is returned by the UNIX command uname .
