Jack,
Prompt those commands, then pressing F1=Help, and then F2=Extended help
to read the full help text..
Then, try this:
1. choose a streamfile in an IFS directory ... (or create a small text
file)
2. do a CHKOUT for that streamfile
3. sign-on to another session as a different user profile, and try to
update that file
4. use WRKLNK to view the streamfiles in that directory, and take
option 8=Display attributes and you can see who has checked out the
file and when ...
5. return to the first session and issue CHKIN for that same stream file
6. now return to the second session to verify that you can now update
or delete that stream file
That's all it does -- it "tags" the streamfile with a userID and
date/time stamp -- and no one else can do anything except read that
streamfile (read-only access), until the original userID does a CHKIN ...
(These commands probably should have been given better names, such as
"Reserve" and "Release" ... )
Hope that helps,
Mark S. Waterbury

Ran into CHKIN and CHKOUT for the IFS and have no idea what they are part
of nor what they do. The help, e.g.
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/cl/chkin.htm ,
has no link to an overall topic. What is "checking in" in this context?
