as long as testing, why bother to add 0?

doubt that optimising the compiler could improve this, because the

It's been too long, would compiler OPT(2) make it better?

Actually, no. I haven’t had a drink in over 30 years.

Certainly if one is looking to save a cycle or two then
if a(i) >= 0 then
sum = sum + a(i);
should be
if a(i) > 0 then
sum = sum + a(i);
because adding a(i) to sum when a(i) == 0 is a waste of a cycle or two.

There has been no announcment, but we have said at SHARE that we would not end
support for COBOL V4.2 before 2020. We are now thinking that we might announce
an EOS date that is before 2020. We don't have a final plan, we are discussing.
I just wanted to give a heads up, it could be sooner than e
I think it is a fool's game guessing which bit of "tricky" source code will
compile into faster executing machine code. Modern machines are plenty fast,
but programmers are not getting any faster. Write maintainable code. Eschew
obfuscation.

I use FTP all the time. Some tricks:
1) The ip address has to be available from SE laptop in the cpu. If you
have the connections between the HMC and the SE on a isolated network,
then the ftp box has to also be on that same isolated network.
2) The 'case' for all items must be correct. Userid,
I was never successful in the past with FTP. Relied instead on a thumb drive,
which worked great but required physical access to the new box.
For our z13s, a colleague was able to get FTP to work. I'm fuzzy on how he did
it, but I think he piggybacked on some outbound but closely connected hard

Ping only proves the stack is up I think, not that the FTP server is up?
I've done this about a year ago when we upgraded to z13s, we loaded or had the
SE load the initial IOCP from a thumb drive, maybe you can try that, the only
successful ftp I've done was reloading (importing) the ICC configu
Listers,
I am having an issue attempting to use FTP to import the IOCP for a new

the HMC and the SE. But when I click " ", I get "File not found on remote
