promptok

[Kapp, Jason]

Hi Terry,
 
I have seen the answer that has been given already and I thought I would
explain why what you originally had didn't work.
There are ten main steps in Accept verb processing the input procedure is
step two, prepare for edit is step 3. As part of step 3 the length of
fieldtext is checked and if it is greater than zero promptok is set to true.
So the reason your code will not work is that promptok has not yet been set
for the current field.
The code you should use to check for null entry in the input procedure is.
 
    IF 0= SIZE(FIELDTEXT)

I have a quick screen where the temporary item T-QTY-REMAINING is used to
allow the user to "skip" entering a value into the field PO-QTY as long as
T-QTY-REMAINING is greater than zero. When it's zero, then the user must
enter something into the field. This part works just fine. However when
T-QTY-REMAINING is less than or equal to zero, it issues the error message
and reprompts for the PO-QTY value. After now entering a value, it still
issues the error message. 


In debug, it shows that after the error is issued AND you re-enter a value
--- the predefined condition PROMPTOK is still FALSE. I would expect it to
now be TRUE since it executed the accept verb again and a value was entered.
This is not happening though. 


Our platform is VAX 710.F4 




PROCEDURE INPUT PO-QTY 

BEGIN 

IF NOT PROMPTOK AND T-QTY-REMAINING > 0 

THEN LET FIELDTEXT = ASCII(T-QTY-REMAINING) 

ELSE 

ERROR "YOU MUST ENTER A QUANTITY" 

END
