Dave, Attached is GEMPAK's pcconv.tbl which is used to convert parameters into other known quantities. The function names represent GEMPAK's library , which is the routine that gets called with the parameters in parentheses. The SAMEPARM operator is useful for relating parameters which may have other names to known parameters. The pcmeth.f routine contains loop for determining the computable parameters (Mary's original development was 1984).
