NAME
     CSMG - Performs a conditional scalar merge

SYNOPSIS
     CSMG ([I=]i, [J=]j, [K=]k)

STANDARDS
     Fortran extension

DESCRIPTION
     The CSMG intrinsic function merges i and j, controlled by the bit mask
     in k.  When a 1 bit appears in k, the corresponding bit of i becomes
     the corresponding bit of the result.  When a 0 bit appears in k, the
     corresponding bit of j is taken.  Therefore, CSMG(i, j, k) equals the
     following specification:

          (i .AND. k) .OR. (j .AND. .NOT. k)

     The CSMG function accepts the following arguments:

     i         First item to be merged.  Can be of Boolean, integer, real,
               or Cray pointer type.  Must be the same length as j and k.

     j         Second item to be merged.  Can be of Boolean, integer, real,
               or Cray pointer type.  Must be the same length as i and k.

     k         Bit mask.  Can be of Boolean, integer, real, or Cray pointer
               type.  Must be the same length as i and j.

     CSMG is an elemental function.  The name of this intrinsic cannot be
     passed as an argument.

NOTES
     The CSMG intrinsic function is outmoded.  Refer to the MIPSpro Fortran
     Language Reference Manual, Volume 3, for information on outmoded
     features and their preferred standard alternatives.

RETURN VALUES
     The return value is of type integer.

EXAMPLES
     Example 1:  Specifying CSMG(i,j,MASK(64)) or CSMG(i,j,-1) yields i.

     Example 2:  CSMG(i,j,0) yields j.

     Example 3:  Specifying the conditional scalar merge
     CSMG('ABCDEFGH'H,'12345678'H,X'0000FFFFFF0000FF') yields '12CDE67H'H
     as the result.
