# Commands covered: string # # This file contains a collection of tests for one or more of the Tcl # built-in commands. Sourcing this file into Tcl runs the tests and # generates output for errors. No output means no errors were found. # # This differs from the original string tests in that the tests call # things in procs, which uses the compiled string code instead of # the runtime parse string code. The tests of import should match # their equivalent number in string.test. # # Copyright (c) 2001 by ActiveState Corporation. # Copyright (c) 2001 by Kevin B. Kenny.
