Menus
File

MEL does not allow you to forward reference locally
scoped procedures. Locally scoped procedure
definitions must appear before they are called. For example, in
a file called noForwardRef.mel,
define the local procedures before they are referenced.
proc myLocalProc() { print "In myLocalProc()\n" ; } proc anotherLocalProc() { print "In anotherLocalProc()\n" ; myLocalProc; } global proc noForwardRef()
{ print "Calling anotherLocalProc()\n" ; anotherLocalProc; }
If you change a script after sourcing it, the change
is not automatically picked up by Maya. You need to re-run the script
with File > Source Script.

Saves the selected text to a text file.
- Save script to shelf
