Re: Nulls in program described file

Infocenter seems to be back up.

ALWNULL

Some of the reasons for internally defining a data file have been 
addressed in the last couple of releases with the 'read into a data 
structure' capability, and others.

Nulls in program described file






I have a little RPG program that is chewing on a file.  The file is an
externally described physical file, but I want to chew on it with a
program described record I/O.  The file has null values in some of the
fields in some of the records.  The program blows up when it tries to
read a record which has nulls.

For example - I have an externally described file with three fields, 10
bytes each.  I set up the file as program described, record length 30.
I create a DS in the program record length 30.  When I read the record
with some nulls, the program bombs.

Any ideas?  In this instance I can't use the file as externally
described.  Trust me on this.  What I'm trying to do is read the record
in as a 30 byte chunk and write it out to an identical file as a 30 byte
chunk.

I can't get at PUBLIB today...

Thanks...
