[ferret_users] accessing environment variables within ferret
Hi,
Is there a way to set a ferret symbol to be equal to an environment
variable that had been set in the environmet from which ferret was run?
It looks like the environment variables are being inherited in the shell
created by the spawn command, so "spawn echo $CASE" is returning the
value of $CASE. But I haven't figure out the magic incantation to get
the result of this into a ferret symbol.
The following doesn't work, but indicates what I'm trying to accomplish:
define symbol CASE = `spawn echo $CASE`
Any suggestions on how to get this to work, or pointers to another
mechanism to retrieve an environment variable within ferret?
Thanks, Keith
