I am trying to write a TCL script on a CSM (Code Ver 4.1) that retains the value of a variable between probe instances (so I can increment and check a variable in each probe attempt). Looking at the documentation there is supposed to be a 'gset' command that does this but cannot make this work.
The example says 'gset var 1 ; incr var'.
I have several problems with this:
1. I would think that this would set the value of var to 1 each time it runs and then increment it (maybe)
2. How can I read the value of the persistent variable without it causing an error if it doesn't exist?
3. It doesn't seem to work anyway as var doesn't appear in the Persistent Variables section of 'show mod csm x tech script'
Any ideas on this or on where I can get some examples where the gset command is used?
