RE: Externalizing I/O was RPG read loops

We used to have a segmented customer master file and associated
transaction history files created when the amount of data was too large
to fit in one file.  We used programs to hide the nasty details of going
from one file to another.  Because RPG file names and record formats
can't be referred to by variables, I don't think that I/O routines give
you very much except in cases where the I/O is more complicated than
just using the standard opcodes. 

IFS file access is a different story.

Paul,

I think you're the first person that I heard of, that wasn't the person
in charge of writing the access programs, that actually liked this
scenario.
Why an end developer would like to replace

chain(e) myfile;
// now actually do some real work with the fields

with
getFilename();
MyWorkField1=GetField(field1);
MyWorkField2=GetField(field2);
...
// now actually do some real work with the fields

rather escapes me.
