Hi All,

Pgm A calls Pgm B.
PGM A.

Accept input (Any one out of 5 possibilities)

CALL PGM B using Input.

|----------------------------------------------------------
|PGM B.
|
|Validate Input.
|
|Opens the related cursor.
|
|Retrieve the row
|
|send the control back to PGM A.
|----------------------------------------------------------

Checks whether all the rows are retrieved or not.

If yes processes the data.

If no again calls the PGM B with an alternate entry point.

My questions here is:

1. Is the second call going to open a new Run Unit? If no, then what happens to the cursor which I opened during the first call but not closed it.

Regards,
MKP
2. What happens to the cursor if the call returns to the Main Program. I am not sure but I think it is still open as our Run Unit is still in progress.

2.

this concerns batch:

1. no same run unit - actually same task. Unless you use the multitask options of cobol3 and start a new task, everything is in the original task.

since you are using entrypoints, that means you are doing a static link which tell me that you are not using cobol3.

2. the cursor is not closed until the task is terminated or the cursor is closed explicitly.

Thanks DB. So if the cursor is not closed and we do a ftech in the subprogram it will continue from the next record, right?

MKP
