I don't know of anyway to (cval('error')) just tells you if its on or off.

Is there any way you can trap the error message and use it somehow, like
a particular SQL value?

No, because I want it for the case where it doesn't exist yet or was cleared but the rest of the command file requires the variable.

Would this work they way you envision?  I think you will still need to
predefine the variable.

SET VAR V1 = NULL

SET VAR VENDKEY TEXT

IF V1 IS NULL THEN
--
DIALOG 'Enter value for v1' v1 vEndKey 1
--
ENDIF
--
RETURN

Hope this helps.

I want to be able to find out if a variable exists and if not to create





it and then pronpt the user to assign a value to it.

I thought I could do something like :

IF (IFEXIST(v1,.v1,NULL)) IS NULL THEN
    DIALOG 'Enter value for v1' v1 vEndKey 1
ENDIF

But I get an error message telling me v1 doesnt exist, Right! I know.
