CVMGN (3sciport)

Performs a conditional merge

SYNOPSIS

  boolean = CVMGN( arg1, arg2, select )

FUNCTION VALUE

  cvmgn           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 CVMGN returns arg1 if select is not equal to zero,
  otherwise arg2 is returned.

NOTES

  Since CVMGN 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 CVMGN
          REAL     CVMGN
          REAL     X
          ...
          X = CVMGN(-1.0,1.0,1)           ! Same as X = -1.0
