Size information is listed in the output files. If you compiled with 64
bit integers on the Origin2000 and 32 bit integers on the O2, it could
certainly be that one would have enough space and the other not. Look for
the section on "Memory type Allocated" in the sander_classic output.

(I'm assuming that the sander_classic test cases run correctly on both
machines. If not, please indicate which one is failing, and how.)

The empty mc0.crd file is probably due to the change in the meaning of
of NTWXM variable, that was not reflected in the printed manuals. See the
"Manual updates" section under "Amber 6 docs" on the Amber web page.

...good luck...dac
