MCS;

Details

The MCS statement puts the QUEST procedure into statement-queuing mode (multiple command submission). That is, PROC QUEST accumulates statements in a 32760-byte buffer before submitting them to SYSTEM 2000. If the accumulated statements fill the buffer, the system displays message -898-. This message instructs you to submit the statements in the buffer by entering two semicolons (;;) or to submit the SCS statement to erase the buffer contents and terminate the MCS mode. You remain in MCS mode until you issue the SCS statement.

The MCS statement is ignored in single-user access mode. In a Multi-User environment, you can use the MCS statement or a Command File to submit a long sequence of SYSTEM 2000 statements that must be processed as a group, for example:

to define a new database or modify an existing definition
to submit statements to the Report Writer feature
to submit a set of IF-THEN/ELSE statements
to submit QUEUE and TERMINATE statement blocks

Issue the RECALL command to bring submitted statements back into the Program Editor. Issue the SAVE command to store the statements in an external file. Then, when you submit the LOCAL COMMAND IS statement, SYSTEM 2000 will process the statements in that file.

If you exit SAS, the MCS buffer is emptied without sending the statements to SYSTEM 2000. To exit SAS and close the database, type BYE on the command line in the Program Editor or submit an ENDSAS statement.

If you submit long strings of statements that terminate with the ENDSAS statement, you must end the SYSTEM 2000 session by using two semicolons (;;) in order to submit the statements to SYSTEM 2000.
