Re: CHKIN/CHKOUT

Yes QDLS and QSYS.LIB and QNTC and friends appears with 3.1 which is
when the entire IFS made it's debut. CHKOUT and CHKIN appeared at that
time.

Prior to this the STUFF in QDLS was in something else that I can't
recall the name of and as I recall was limited to a fairly minimal size
as we tried to use them to back up PCs at one point. 32MB Maybe? (It
certainly wasn't GBs as we had only 600 MB Total disk!!!

PC support on the System/38 brought in those commands. I remember getting
excited when I thought I would be able to stop the growth of the PC storage
(We did not have "servers" ye) in the company and centralize into one
sharing environment. But at twinax speeds it was just not possible, and
the only PCs that could play were the ones with emulator cards in them,
which only a third had.

from my memories..
The possibility to use virtual disk appeared in S/38 (and S/36) was part
of S/3X PC support and the first versions of PCS/AS400

in AS/400 (I think it was already in the first release) there were Folders
and Documents Library Objects stored in the library QDOC and mainly used
by Office/400
This was a Hierarchical File System like optical disks...
I do not remember there was a possibility to use checkin-checkout with
folders, this was done by applications like WAF/ImagePlus.

When the IFS appeared with V3R.1, QDLS was the new name of the file system
to the DLO's .... it came with chkin/chkout...

IMHO, CHKIN/CHKOUT commands are not old stuff. They are very useful in
document management (version control) applications.
using those command to check the existence of an object is certainly not a
good idea...

Those commands are hold overs from the System/38 days. Not of much

S/38? Are you sure?

I'm pretty sure that S/38 didn't have IFS.

Did the S/38 have QDLS?
