Synopsis
This is an error in the way the REXX script is written. There is a ELSE keyword without some expression after it.
Cause
You tried to name a variable else in a place where the ELSE keyword is illegal.
Cure
In certain instructions, you cannot use the (unquoted) REXX keyword ELSE for a variable name.
Cause
You put an ELSE keyword, but wanted no particular action taken so you left it blank after the ELSE.
Cure
You should use the NOP keyword if you want no particular action taken.
