I'm familiar with that area of storage, but only by passing. What about that confuses me is this --
During my long nights of testing I've noticed that often the storage addresses of certain Rexx control blocks stay the same. Now, I don't know if they are they same by accident or they are constant throughout my TSO session. The docs (AFAIK) don't elaborate on this. And I would never think something would be some way without seeing in b&w. Also, I've been thinking about how to ask this for about 2 days and I still don't know how to ask. Here goes: A Rexx function, like SOCKET, is called that INITALIZES (something) and then you do things by calling SOCKET() that keep you seemingly in constant communication with a "process" that is acting on your behalf. Like reading from a socket. What is going on that allows a call to a Rexx function to start a "process" that does something and then communicate with and send commands through it? Normally the Rexx functions I've seen start, process something, create or alter Rexx variables, and then end.

If it's not already set you can allocate your storage and save the address there. Things get more complicated if it might already be set. You'd have to have some way of telling if it is yours. (Take the following with a very large grain of salt. Maybe a block of salt.) If you can tell the value in ENVBLOCK does not belong to you, maybe you can create a new environment to use. Then you have to be able to find your environment the next time you are invoked. It's been almost 20 years since I'written REXX functions so I don't remember any of the details to go with the above comments. :-( Pat O'Keefe ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
