Defines the conversion of data in formatted data transfer
  operations.  Statement format:

     FORMAT (q1 f1s1 f2s2 ... fnsn qn)

     qn   Is zero or more slash (/) record terminators.

     fn   Is a data edit (field) descriptor, a control edit
          descriptor, a string edit descriptor, or a group of
          such descriptors enclosed in parentheses.

     sn   Is a field separator (a comma or slash).  A
          comma can be omitted in the following cases:

          o Between a P edit descriptor and an immediately
            following F, E, D, or G edit descriptor.

          o Before or after a slash (/) record terminator.

          o Before or after a colon (:) edit descriptor.

  The "data edit descriptor" has one of the following forms:

     [r]c  [r]cw  [r]cw.m  [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,O,Z,F,E,EN,ES,D,G,L, or A).

     w    Is the external field width in characters.  Each
          data item in the external medium is called an
          external field.

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

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

     E    Is an exponent field.

     e    Is the number of characters 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 unsigned integer constants or variable format
  expressions.  A variable format expression is an integer variable
  or expression enclosed in angle brackets that takes the place of an
  integer constant.  The value of the variable or variables can
  change during program execution.

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

  The "control edit descriptor" has one of the following forms:

     c  [n]c  c[n]

     c     Is a format code (X,T,TL,TR,SP,SS,S,BN,BZ,P,
           Q, $, or :).

     n     Is an optional number of characters or character
           positions.

  The term "n" must be an unsigned integer constant (for format code
  P, it can be signed or unsigned) or a variable format expression.
  A variable format expression is an integer variable or expression
  enclosed in angle brackets that takes the place of an integer
  constant.  The value of the variable or variables can change during
  program execution.

  The value of "n" for P must be within the range -128 to 127.  For
  all other format codes, the value of "n" must be within the range 1
  through 2147483647 (2**31-1); actual useful ranges may be
  constrained by record sizes (RECL) and the file system.

  The "string edit descriptor" has one of the following forms:

     "string" 'string'  nHc1...cn

     string  Is a character literal constant.

     n       Is the number of characters to be transferred.

     c1...cn Is a string of printable ASCII characters.

  Although no string edit descriptor can be preceded by a repeat
  specification, a parenthesized group of string edit descriptors can
  be preceded by a repeat specification.
