nPFw.d

 On output, the value of the I/O list element is multiplied by 10**n
 before transfer to the external record.  Thus, a positive scale
 factor moves the decimal point to the right; a negative scale
 factor moves the decimal point to the left.  Thus, the F field
 descriptor alters the magnitude of the data.

 nPEw.d

 On output, the basic real constant part of the I/O list element is
 multiplied by 10**n, and "n" is subtracted from the exponent.  For
 a positive scale factor, "n" must be less than d+2 or an output
 conversion error occurs.  Thus, a positive scale factor moves the
 decimal point to the right and decreases the exponent; a negative
 scale factor moves the decimal point to the left and increases the
 exponent.

 nPGw.d

 On output, the effect for the G field descriptor is suspended if
 the magnitude of the data to be output is within the effective
 range of the descriptor (because the G field descriptor supplies
 its own scaling function).  It functions as an E field descriptor
 if the magnitude of the data is outside its range.  In this case,
 the scale factor has the same effect as for the E field descriptor.
