      DESCRIPTION...
       A CCC FILE ARITHMETIC PROGRAM WHICH...
 
       ... PRODUCES FILE XOUT = A*XIN + B
           (WHERE BOTH XIN AND XOUT MAY CONTAIN REAL OR COMPLEX
            DATA TYPES, BUT B MUST BE 0.0 FOR COMPLEX FILES.
            Please see Note 2) below for mode details)
 
 
      PARAMETERS...
 
       A    = REAL MULTIPLICATIVE CONSTANT. 
       B    = REAL ADDITIVE CONSTANT. 
       NAME = NEW NAME TO BE GIVEN TO THE OUTPUT RECORDS.
              DEFAULTS TO THE ORIGINAL NAME
       NPG  = (OPTIONAL) OUTPUT PACKING DENSITY
 
 
       READ( 5,5010 ) A,B,NAME,NPG
 5010  FORMAT(10X,2E10.0,1X,A4,I5)
 
 
      NOTES: 1) MISSING VALUE TREATMENT IS SUPPORTED VIA EITHER THE
                "MISSING_VALUE" ENVIRONMENT VARIABLE OR THE "-mvalue"
                COMMAND-LINE ARGUMENT. PLEASE SEE THE R.DIAG WEB
                DOCUMENTAION FOR MORE DETAILS.
             2) IF "-def SPECTRALB" IS SPECIFIED ON THE COMMAND-LINE,
                A NON-ZERO VALUED B CONSTANT IS ALSO APPLIED TO SPECTRAL
                FIELDS VIA A MODIFICATION TO THE REAL PART OF THEIR (0,0)
                COEFFICIENT SCALED BY SQRT(2.), THE LEGENDRE NORMALISATION
                FACTOR USED IN THE CURRENT SPECTRAL TRANSFORMS.
             3) IF *BOTH* A AND B ARE LEFT UNSPECIFIED (AND NOT 0), *AND*
                IF THE PROGRAM IS INVOKED IN COMMAND-LINE PARAMETER MODE,
                THEN A AND B ARE SET TO +1.0 AND 0.0, RESPECTIVELY.
