This probably won't help you very much but on the Unix side of things (at
least on HP-UX, where I've used it before) there is the "glob()" function
in the C library. You pass it a string containing your wildcarded file set,
and it returns a pointer to an array of strings containing the filenames of
all the files that matched your file set.

I would be very surprised if the gcc environment, which has been ported to
MPE/iX, did not contain some variant of glob(). If you were to install gcc
on your system, you might be able to call glob() from within COBOL.

There may be information on how you can call C library functions from
within COBOL in the multi-language programming paper on Jazz:
