+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.
