 This routine is the main body of ICMULT,ICDIV,ICADD and ICSUB,
 and of XCMULT, XCDIV, XCADD and XCSUB.  The Ixxxx routines
 operate on the data in an image, the Xxxx routines operate on
 the data in the X array of the input file.
 ICMULT multiplies an image by a constant.  Since the constant
 can be less than 1., this function will also divide an
 image by a constant, but ICDIV saves the caller from having
 to calculate a reciprocal. ICADD adds a constant to an image and
 ICSUB subtracts a constant from an image.

 Command parameters -

 IMAGE  (Character) The name of the structure containing the image.
        Uses main data array, or the x-axis data for the XCxxx routines.

 FACTOR (Numeric) The value of the constant factor.

 OUTPUT (Character) The name of the result of the operation.  This
        can be the same as for IMAGE.  If not, a new structure
        is created, with everything but the data a direct
        copy of the input.

 The command name is used to distinguish between the
 possible operations.
