You could consider having a "file owning" TCB (FO-TCB) within your server, design structures that describe "a file" and "a file action request" and then you can send requests to some sort of queue monitored by the FO-TCB from your sub-tasks to open or close files.
Your ESTAEs (or RESMGRs or EOT exit routines) can then just place a request on the FO-TCB request queue to close the file.

This uses sub-tasks to do I/O. When I designed my program using DSTs I had a problem I could not resolve. I have been informed by IBM that sub-tasks are suspended during an abend and cannot be used. This means there is no way to close the files opened by the sub-tasks in my estae routine. Has anyone come with a solution to this problem? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
