RE: [EXTERNAL] Re: [RBASE-L] - Checking Variables

[Razzak Memon]

Here is how I use the (CHKVAR('varname)) function in all my applications when it is required.

 

IF (CHKVAR('vVarName)) <> 1 THEN
   SET VAR vVarName vartype = NULL
ENDIF

 

That way, without any -ERROR—message, etc., if the variable in question exists, nothing happens; if it doesn't exist, it creates one with a NULL value.

 

Very Best R:egards,

(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.

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?
