COBOL SORT problem

COBOL SORT problem

COBOL SORT problem


I have a proble with Visual Age COBOL Sort.

See the program call sequence given below.


SUB1 is invoked from MAIN multiple times, SUBIO is the module that handles file operations and SORTS for multiple files. The problem is that if SUB1 is invoked multiple times(say >100) the application terminates during the execution without showing any error. If it is invoked lesser nr. of times(say 10), it would be fine.
I found the problem is in SUBIO, SORT that uses i-o procedures. After removing each the SORT from SUBIO,the situation became better. Finallly, I could replace the COBOL SORTs with a C routine. Now application runs without a crash.
Any body faced such a problem in COBOL SORT? Thanks
