4000.0. "Validation & Decimal(x,y) type fields?" by PTOSS1::HRIADILM () Wed May 21 1997 10:13

    
    Question on validation...
    
    Have a COBOL program which passes the following fields into a form.
    
    	Field Name		COBOL defn	Forms defn
    	===============		==========	===========
    	ORIGINAL_AMOUNT		S9(6)V99	Decimal(6,2)
    	AMOUNT_1		S9(6)V99	Decimal(6,2)
    	AMOUNT_2		S9(6)V99	Decimal(6,2)
    
    The user can modify AMOUNT_1 and AMOUNT_2. This all seems to be working
    fine - i.e., the data goes into the form ok and after modifications
    appears to be ok back on the COBOL side.
    
    I need to add a validation such that the sum of AMOUNT_1 and AMOUNT_2
    must equal ORIGINAL_AMOUNT in order to be valid.
    
    I want to do this in a validation response on field AMOUNT_2 but so far
    have not been successful.
    
    Can fields of type Decimal(x,y) be maninuplated mathematically in the
    form? 
    
    Any suggestions would be appreciated.

    Read the NUMERIC EXPRESSION section in the DECforms IFDL reference
    manual, I am pretty sure you can not use decimal data types.
    
    You could call an escape routine in the validation response to
    do the validation for you.

    Got it to work via an escape routine. Thanks...
