Another thing to consider is the version of the HP COBOL
compiler you are using.

When HP came out with large file support on 6.5 they changed
COBOL to use the newer 64-bit compliant back-end which references
64-bit compatible routines.

CPU intensive integer access are considerably slower with this
version of the compiler. See http://qwebs.qss.com/cobdata.html
for some examples of this.

HP has since changed the compiler to use the previous
back-end (32-bit) so if you have 6.5-7.5 of mpe and have installed
all the latest cobol patches you would have the mpe 6.0 performance
equivalent. However, if you are on 6.5-7.5 and don't have the
patched COBOL then you are generating slower code for anything that
references integers.

For more details you might want to search the archives, specifically
for anything written by Walter Murray ex-of HP.
