correct. such primitive technology, who could be bothered!

I stand corrected.  Most of the places I worked were mixed 36/38/400 shops.
The 36 people I worked with were all a lot of fun to work with.  Very
respectful of their 38 mentors who always found the time to help them out.

which explains why rpgIII had all that useless stuff in it. SPECIAL files,
matching records, ...

But hardly any iSeries applications run in the 36 environment anymore.  So
we are back to running what was and is the System/38.  Other than tcp/ip, I
think only journaling and a more user friendly query have been added to
os400 from what cpf had to offer.
