Reply To: Sharing globals btwn conns in outbound tcl interpreter

[Charlie Bursell]

Global variables are only global within the same Tcl interpreter.  Each Cloverleaf process has its own interpreters.  There are three interpreters within a process, IB, Xlate, and OB.

So a an ob_sms-data_proc could share a global with a reply proc for example.

Take a look at the recover_33 proc, it is based on sharing of a global.  But note that all 3 procs are in the OB thread of the same process.

Remember when you run a process, you are running a separate instance of the program.  An analogy would be to run ftp and then run another instance of ftp.  Niether is aware of the existance of the other.
