`ENCODE' and `DECODE'
---------------------

   `g77' doesn't support `ENCODE' or `DECODE'.

   These statements are best replaced by READ and WRITE statements
involving internal files (CHARACTER variables and arrays).

   For example, replace a code fragment like

           INTEGER*1 LINE(80)
     ...
           DECODE (80, 9000, LINE) A, B, C
     ...
     9000  FORMAT (1X, 3(F10.5))

with:

           CHARACTER*80 LINE
     ...
           READ (UNIT=LINE, FMT=9000) A, B, C
     ...
     9000  FORMAT (1X, 3(F10.5))

   Similarly, replace a code fragment like

           INTEGER*1 LINE(80)
     ...
           ENCODE (80, 9000, LINE) A, B, C
     ...
     9000  FORMAT (1X, 'OUTPUT IS ', 3(F10.5))

with:

           CHARACTER*80 LINE
     ...
           WRITE (UNIT=LINE, FMT=9000) A, B, C
     ...
     9000  FORMAT (1X, 'OUTPUT IS ', 3(F10.5))

   It is entirely possible that `ENCODE' and `DECODE' will be supported
by a future version of `g77'.
