old question : same problem

Hi

Set up a batch queue that only allows one job at a time.

Just write a DCL script (submit to the above queue) to do a dir of the 
receive directory which then moves all the files to a process directory and 
submits each file to a standard script to the batch queue. The standard 
script will run the program with the file (from the process directory using 
a file equate) then transfer the file to a processed directory (if 
successful). The original script will resubmit itself, which should run 
again after all the files have been processed If there are no files to be 
processed you might want to delay the resubmit for a period of time.

Net result is that unprocessed files will be in the receive dir, processed 
files will be in the processed dir and any unprocessed or files with 
problems will be in the process dir.

The main problem is how to stop processing of a file if the users has sent, 
exactly the same data twice, with or without differing file names.

You may also want to append a date/time stamp in the file name when you 
move the file to the process directory to facilitate identifying when files 
where started processing.
