Hi,

Here is my scenario,

I have a file declared and opened in output mode in main program. I call sub module for some process and at the end of the process i should write the data to the file(which is opnd in main program) in sub module.

Say my linkage is of same structure as the ouput file declared in main module.

I dont want the file to be opened/closed in sub module because sub module may be called n number of times by main program.

Pls help me how to handle this in sub module?

There is a link to manuals at the top of the page. Find the COBOL Language Reference manual, do a search on "external file" and read up on what you need to do to use them.
