ELSE has no corresponding THEN clause

Synopsis
This is an error in the way the REXX script is written. Some ELSE keyword appears where it should not be.

Cause
You forgot to put a THEN keyword before the ELSE keyword.

Cure
ELSE can't be used without a preceding THEN. Make sure that, for every ELSE, there is one matching THEN before it (although there may be a preceding ELSE inbetween).

Cause
You tried to name a variable else in a place where an ELSE keyword would be illegal.

Cure
In certain instructions, you cannot use the (unquoted) REXX keyword ELSE for a variable name.
