21: c based on specifications as defined in american national standard ! 22: c programming language fortran x3.9-1978, has been developed by the ! 23: c federal cobol compiler testing service. the fortran compiler ! 24: c validation system (fcvs) consists of audit routines, their related ! 25: c data, and an executive system. each audit routine is a fortran ! 26: c program, subprogram or function which includes tests of specific ! 27: c language elements and supporting procedures indicating the result ! 28: c of executing these tests. ! 29: c ! 30: c this particular program/subprogram/function contains features ! 31: c found only in the subset as defined in x3.9-1978. !
