Re: Best method to determine if more than one field not blank

Bob,

You could have them all defined in a DS and then check the trimmed length of
the DS...

D Fields DS
D Fld1 1A
D Fld2 1A
D Fld3 1A
D Fld4 1A

if %len( %trim( Fields ) ) > 1;
exsr error;
endif;

I have four 1 char fields and I only want 1 of the four to be able to
contain a char at a time. I could check each field after it returns from
the
screen and add 1 to a variable if it is not blank and if the variable is
greater than 1 return an error.

Is there a better way to do this?

Thanks,
Bob B
