Showing IRIX 6.5.30 (default release). Last changed in IRIX 6.5.19.
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.
