c
c this routine contains basic arithmetic if statement tests.
c the statement format is
c if (e) k1, k2, k3
c where e is a simple integer expression of form
c variable - constant
c variable + constant
c and k1, k2 and k3 are statement labels. only the statements in
c the basic assumptions are included in these tests.
c execution of an if statement causes evaluation of the
c expression e following which the statement label k1, k2 or k3
c is executed next as the value of e is less than zero, zero, or
c greater than zero, respectively.
c
c the basic unconditional go to statement is tested in this
c routine. the statement is of the form
c go to k
c where k is a statement label.
c execution of an unconditional go to statement causes the
c statement identified by statement label k to be executed next.

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