Wait for program invoked via $TsoAtt to complete
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $TSOWait function.
This function waits for a program invoked via $TsoAtt to complete.
This function requires the special version of the TSO full screen interface to Model 204 that is distributed by Sirius Software.
The $TSOWait function accepts two arguments and returns a numeric completion code or task id.
The first argument is a number that is the task id of the "task" to be waited on. This task id is returned by $TsoAtt at program invocation time.
The second argument is string containing the name of an image to receive output data from the invoked program. This is an optional argument.
Syntax
<section begin="syntax" /> %RESULT = $TSOWait( task_id, out_image ) <section end="syntax" />
$TSOWait normally returns the completion code from the invoked program. If there is some error that prevents the program from being invoked, however, a negative error code is returned to indicate the problem.
-1 - Connection broken -4 - Not a TSO full screen IODEV (IODEV 11) -8 - Incorrect version of TSO interface -16 - Image not found -20 - LOUTPB too small
The following program invokes a program called 'COMPRESS' in the user's TSO address space with a parameter of 'DSN(JUNK.CNTL)', issues a FIND while 'COMPRESS' is running and then waits for the 'COMPRESS' command to complete.
B %TASKID = $TsoAtt( 'COMPRESS', , 'DSN(JUNK.CNTL)') FIND1: IN BIGFILE FIND ALL RECORDS FOR WHICH NAME IS LIKE 'SM*' END FIND %RC = $TSOWait( %TASKID ) ... END
