$TSOWait
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.
Note: 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.
Syntax
%result = $TSOWait( task_id, out_image )
Syntax terms
| %result | Either the completion code from the invoked program or an error code. |
|---|---|
| task_id | 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. |
| out_image | A string containing the name of an image to receive output data from the invoked program. This is an optional argument. |
Error codes
$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
Example
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
