(CHKVAR('varname'))
Checks to see if a variable name exists. The function returns an integer value of 1 if the variable name exists or declared, and 0 if it is not found or declared.

Subject [RBASE-L] - Checking Variables
I am looking for a way to check to see if a variable has been created.
Does anyone know a way to see if a variable has been created?
