Re: FW: data mapping error

Angela,

When you try to do anything with the field, do you check to see if it is
null first?

I believe that even if you specify ALWNULL(*USRCTL), you still have to
check for null before using it.

I do something like this:

c           if    %nullind(fldname)
c           eval  %nullind(fldname) = *off
c           eval  fldname = *blanks   ...(or 0)
c           end

good luck,

Rick

    I have an ILE program that is reading files that were created with a
SQL script.  Some of the fields in the file are null-capable.  I have
compiled the program with *USRCTL on the allow null value field.   This
USUALLY takes care of getting any errors for null fields.   However once
in a while I will get a data mapping error within an ILE program while
reading a particular file.   All I do is go into that file & record it
is bombing on and blank through any of the blank fields.   Then
everything is fine.   Why does it bomb out if I have used *USRCTL?
What can I do to prevent this?

Thankyou!!
