# Commands covered: proc, return, global
#
# This file, proc-old.test, includes the original set of tests for Tcl's
# proc, return, and global commands. There is now a new file proc.test
# that contains tests for the tclProc.c source file.
#
# Sourcing this file into Tcl runs the tests and generates output for
# errors. No output means no errors were found.
