If you didn't follow the "Directed Load" thread on ASSEMBLER-LIST, the OP was seeking a technique for installing an updated version of a load module while it might be in use by some threads without disrupting the execution of those threads. I was imagining that by loading JOE while active threads were executing WOMBAT, those threads would run to completion and when the reference count beame 0, FRED would be removed from storage. Meanwhile, new threads linking to WOMBAT would get the updated version in JOE. -- gil ---------------------------------------------------------------------- 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
