CVMGP (3sciport)

Performs a conditional merge

SYNOPSIS

  boolean = CVMGP( arg1, arg2, select )

FUNCTION VALUE

  cvmgp           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 CVMGP returns arg1 if the sign bit of select is set
  to zero, otherwise arg2 is returned.

NOTES

  Since CVMGP 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 CVMGP
          LOGICAL  CVMGP
          LOGICAL  P
          ...
          P = CVMGP(.TRUE.,.FALSE.,-1.0)  ! Same as P = .FALSE.
