Synopsis
A label that the interpreter needs to find in your REXX script is not found. name is the name of the label that you specified.
Cause
You did a SIGNAL to a particular, named label, but never actually put that label in your script.
Cure
Make sure that the label name appears somewhere in your script, followed by a semi-colon.
Cause
You specified a SIGNAL ON <some condition such as SYNTAX>, never specifying a particular label name, but also forgot to put a label with the name of that condition.
Cure
If you put a statement such as SIGNAL ON SYNTAX (without the keyword NAME followed by some label), then you must have a label somewhere in your program called SYNTAX, followed by a colon. The interpreter will jump there when a SYNTAX condition occurs.
