Environment variables are available to Tcl scripts in a global associative array env . The index into env is the name of the environment variable. The command puts "$env(PATH)" would print the contents of the PATH environment variable.
In side tcl script, you can simply do setenv as, setenv AUTOTEST="/auto/isbutest/frt" . if you want to set a variable, use set VARNAME "/auto/isbutest/frt" . if you want to get any environment variable, use $::env(AUTOTEST) .
Use $::env to access any environment variables e.g. to access the TMP environment variable do this:
set tmpdir $::env(TMP) More info here http://wiki.tcl.tk/1624
