# Commands covered: incr

#
|

|
|
# This file contains the original set of tests for Tcl's incr command.
|
||
|
|
# Since the incr command is now compiled, a new set of tests covering
|
||
|
|
# the new implementation is in the file "incr.test". Sourcing this file
|
||
|
|
# into Tcl runs the tests and generates output for errors.
|
||
|
|
# No output means no errors were found.
