Makes sense. They are becoming fewer as I gain experience.

I hope that I am missing something.
The STCKE instruction, an unprivileged one, yields a 16-byte value at
a nominated storage location.
The difference between two such values, trimmed of their two rightmost
bytes (the programmable field), yields an elapsed time.
This value can then be formatted
John,

Yea- it is a different thread (assumption based on the next
sentence/citation)
Any leap-second corrections would, for example, be washed out

No use of the TIME macro need or should figure in this operation. Any
leap-second corrections would, for example, be washed out by the
subtraction:
(T + L) - (t + L) = T + L - t - L = T - t.
Why all this pother?
And even if a leapsecond was inserted between the start- and endtime the

Does anyone have a clist or program that can convert an assembler copybook to a
cobol copybook ?

Good idea. But does not free up the base register currently being used, for
other purposes. I have cheated again. I created a __LA macro which looks at
the first character of the name. If it is not a !, I generate the code for a
normal LA instruction. If it is a !, I strip it off and generate

John,
I have been using a slightly different method.
I have been constructing local versions of various macros incorporating the

BAL instructions are replaced by BRAS instructions ; however, I have
