Just use
SET VAR v1 TEXT
... or whatever datatype is is delcared to as before. Be sure to keep the datatypes the same though..
Don't set it to null. Doing it this way will not clear the variables setting if it already exist, but well set it to NULL if it doesn't exist.

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.
