There should be an easy way to do this, but I can't seem to find it.
What command can I run in Tcl to make it peek in and report the running version?
info patchlevel
which is the tcl_patchlevel value
see tcl tutorial
You only need
puts $tcl_patchLevel
in addition to other parameters, you can use:
puts $tcl_version
This has the advantage that you are running comically old versions of tcl.
