To compile an application that calls the routines in the MASS libraries, specify massvp4 (32-bit) or massvp4_64 (64-bit) on the -l linker option. For example, if the MASS libraries are installed in the default directory, you could specify one of the following:
xlf progf.f -o progf -lmassvp4 xlf progf.f -o progf -lmassvp4_64 -q64
The MASS functions must run in the round-to-nearest rounding mode and with
floating-point exception trapping disabled. (These are the default
compilation settings.)
