Syntax:

 return

Return is used to force the script to stop processing. This can be useful inside if statements where you want to prevent lines following the return from being processed.

-I had a glitch in a script, and careful debugging has taught me that RETURN is a little more powerful than first suspected.
-The scripts are designed with the BEGIN <event> syntax.
-I was considering these independednt functions called seperately.
-However if within the same frame execution you have more than one <event> expected to be processed, and use RETURN in the first <event> for any reason. No other <event>s will be processed.
-The clear example I discovered, was using RETURN within an OnLoad event. Which ultimately glitched the necessary OnReset event. Because OnLoad and OnReset are processed at the same frame during a cell load the OnLoad event exited the script before the OnReset had a chance to process.
-''Begin OnLoad
-  If doOnce == 1
-    Return
-  Endif
-  ; Stuff to do once
-End
-Begin OnReset
-  ; Stuff to do every Reset
-End''
-The "stuff to do every reset" will only process the one time OnLoad processes.
-RETURN as clearly stated in the Wiki exits the script, not the OnLoad function.
-Just thought I would add this bit of business so others would not make the same mistake I did. I hope it helps.
