tablebase sorting in COBOL-390 1

[manojgovindan]

Hi all,

I used tablebase sorting in one of my subroutines.
Everytime the driver pgm calls the subroutine, it creates a new table and deletes it before return to main program. The driver calls the subpgm many a time and will this cause performance problem? Is there any alternative using which I can avoid redefining the table everytime.

To define table
MOVE 'DT' TO TABLEBASE-COMMAND-ID
To close table
MOVE 'CL' TO TABLEBASE-COMMAND-ID
The call
CALL 'TBCALLI' USING TABLEBASE-COMMAND-AREA
TABLEBASE-DEFINE-AREA.

any help is much appreciated

Thanks,
Manoj

1. Define the table ('DT' command)
2. Populate the table, retrieve & process the data etc
3. Empty the table ('MT' command)
4. Repeat steps 2-3 as many times as necessary
5. Close the table ('CL' command)
