OS/390 specifics: host call

Syntax

CALL SLEEP(time);

time: specifies the amount of time, in milliseconds (1/1,000 of a second), that you wish to suspend execution of a DATA step and the SAS process that is running that DATA step.

Details

CALL SLEEP puts the DATA step in which it is invoked into a nonactive wait state, using no CPU time and performing no input or output. If you are running multiple SAS processes, each process can execute CALL SLEEP independently without affecting the other processes.

In this example, the DATA step invokes CALL REPORT every hour:

data _null_;
   while (1);
      call report(a,b,c,d);
      call sleep(3600000);
   end;
run;

Note: In batch mode, extended sleep periods can trigger automatic host session termination based on timeout values set at your site. Contact your host system administrator as necessary to determine the timeout values used at your site. [cautionend]
