CVMGZ (3sciport)

Performs a conditional merge

SYNOPSIS

  boolean = CVMGZ( arg1, arg2, select )

FUNCTION VALUE

  cvmgz           Boolean. (Integer, Logical, or Real.)
                  The result of the conditional merge.

ARGUMENTS

  arg1            Integer, Logical, or Real.
                  An input argument.

  arg2            Integer, Logical, or Real.
                  An input argument.

  select          Integer, Logical, or Real.
                  The select argument.

DESCRIPTION

  The external function CVMGZ returns arg1 if select is equal to zero,
  otherwise arg2 is returned.

NOTES

  Since CVMGZ is not an ANSI Fortran 77 intrinsic function, it must be
  declared as an external function of type integer, logical or real. For
  example:

          EXTERNAL CVMGZ
          REAL     CVMGZ
          REAL     X
          ...
          X = CVMGZ(-1.0,1.0,1)           ! Same as X = 1.0
