The only thing that occurs to me is that COBOL tends to use the simplier, older
instructions. Are you using the more powerful z instructions? An example that I
was told about is that MVC in a loop is generally faster than MVCL and both are
faster than MVCLE. So, in many case, a simple loop is better than a more
powerful single instruction. If I'm wrong on this, I'm sure to be corrected.
I've also heard that using the 64 bit instructions (such a AG rather than A)
are actually faster. So you might consider using something like:
LGF R10,FULLWORD
instead of the older
L R10,FULLWORD
then use the Grande (64 bit) arithmetic instructions. This is hearsay, I don't
have experience with it.
