NAME

SYNOPSIS
source fileName
source-rsrc resourceName ?fileName?
source-rsrcid resourceId ?fileName?
_________________________________________________________________
DESCRIPTION
This command takes the contents of the specified file or
resource and passes it to the Tcl interpreter as a text
script. The return value from source is the return value of
the last command executed in the script. If an error occurs
in evaluating the contents of the script then the source
command will return that error. If a return command is
invoked from within the script then the remainder of the
file will be skipped and the source command will return
normally with the result from the return command.
The -rsrc and -rsrcid forms of this command are only
available on Macintosh computers. These versions of the
command allow you to source a script from a TEXT resource.
You may specify what TEXT resource to source by either name
or id. By default Tcl searches all open resource files,
which include the current application and any loaded C
extensions. Alternatively, you may specify the fileName
where the TEXT resource can be found.
