- I've never done this but... I can offer you a quick method to change
- the value.
-
- The value for WSMAX is stored at the symbolic address SGN$GL_MAXWSCNT.
- You can change this value WHILE THE SYSTEM IS RUNNING with DELTA. How?
- Lookup the address of SGN$GL_MAXWSCNT in SYS.MAP. Then, enter DELTA.
-
- $ RUN SYS$SHARE:DELTA
- 1:m <cr>
- 00000001 <cr>
- 00010001:<address of SGN$GL_MAXWSCNT>/<return-curr-value> <your-new-value>
- EXIT (hex of course)
- $

- >Caveats ? :-)

- This above will change the value. Its implications if you increase it
- above the current limits? I know not! I just LOWERed my system's WSMAX
- by 16 with the above and have had no problems.
-
- If you have a system you can crash... try it out and let us know.
