Data_Edit_Format

 A data edit descriptor takes one of the following forms:

    [r]c  [r]cw  [r]cw.m  [r]cw.d [r]cw.d[Ee]

    r    Is an optional repeat count.  (If you omit "r", 
         the repeat count is assumed to be 1.)

    c    Is a format code (I,B,O,Z,F,E,EN,ES,D,G,L, or A).

    w    Is the total number of digits in the field (the
         field width).

    m    Is the minimum number of digits that must appear 
         in the field (including leading zeros).

    d    Is the number of digits to the right of the decimal point.

    E    Identifies an exponent field.

    e    Is the number of digits in the exponent.

 The ranges for "r", "w", "m", "d", and "e" are as follows:

 Term      Range                 
 ----      __________                 
  r        1 to 2147483647 (2**31-1)  
  w        1 to 2147483647            
  m        0 to 32767 (2**15-1)       
  d        0 to 32767                 
  e        1 to 32767                 

 The terms must all be positive, unsigned, integer constants or
 variable format expressions.

 You cannot use PARAMETER constants for "r", "w", "m", "d", or "e".
