This is a very simple 7-segment character editor. It is suitable
for very small systems where you wish to manipulate the display
bit patterns directly instead of using a translate table.


use:    EDIT7S filename [options]

opts:   B=bbbbbbbb      - segment Bit order             [76543210]
        /L              - decimal point on Left

It reads a source file containing 'EQU' statements for the character
definitions, and allows interactive editing with visual display of
the 7-segment patterns (see on-screen help).

Each display character is represented by a byte value, with a bit for
each segment. The default organization of bits to segment is:

     0
   5   1
     6
   4   2
     3   7

You can specify a different bit mapping with the B= command line option,
where each each bit position correspond to the segments above:

   B=76543210   - No change
   B=73546210	- Interchange segments 6 and 3

Limits:

 - Max 32 lead-in comments, no more than 127 characters each
 - Max 128 character definitions
 - Max 8 character label fields
 - Max 63 character comment fields
