# This file contains tests for the tclProc.c source file. Tests appear in # the same order as the C code that they test. The set of tests is # currently incomplete since it includes only new tests, in particular # tests for code changed for the addition of Tcl namespaces. Other # procedure-related tests appear in other test files such as proc-old.test. # # Sourcing this file into Tcl runs the tests and generates output for # errors. No output means no errors were found. # # Copyright (c) 1997 Sun Microsystems, Inc. # Copyright (c) 1998-1999 by Scriptics Corporation. # # See the file "license.terms" for information on usage and
