     The following programs and tips are examples of ways to make your
     BASIC programs look more structured.
     
     First of all it is always best if you are writing a large program to
     break it up into several subroutines. These subroutines could make use
     of variables so as to function differently depending on what part of
     the program is calling them.
     
     To give your subroutine an appearently REMless title do the
     following:
          1) Enter the REM on desired line
             followed by a quote (").
          2) Press <CR>
          3) Cursor up to that line and
             to the right of that quote
             turn on reverse mode (CTRL
             RVS-ON).
          4) Now press SHIFT M and SHIFT Q.
          5) Press the quote again then
             delete it.
          6) Enter the comment you wish to
             be entered as a REMark.
          7) Press quote and then delete
             it.
          8) RVS-ON.
          9) Next SHIFT Z.
         10) Finally, <CR>.
     That's all there is to it! I can't take credit for this one. It
     belongs to Luis Pistoia of Argentina.
     
     To produce the indentation effect found in certain PASCAL and C
     editors, use the colon (:). That's all! The following give examples of
     what I mean:
     
     ----------
     PROGRAM #1
     ----------
     10 :FOR I = 1 TO 10
     12 :   FOR J = 1 TO 10
     14 :      FOR K = 1 TO 10
     16 :         PRINT
     18 :         PRINT
     20 :         PRINT
     22 :         PRINT K,
     24 :         PRINT J,
     26 :         PRINT I
     28 :         PRINT
     30 :         PRINT
     32 :         PRINT
     34 :      NEXT K
     36 :   NEXT J
     38 :NEXT I
     

     ----------
     PROGRAM #2
     ----------
     10 :REM   THIS IS AN EXAMPLE IN
     12 :REM   STRUCTURED PROGRAM DESIGN
     14 :REM
     16 :BEGINNING=1: FINISH=12
     18 :FOR LOOP = BEGINNING TO FINISH
     20 :   PRINT "LOOP #"; LOOP
     22 :   PRINT: PRINT: PRINT
     24 :NEXT LOOP
     99 :STOP
     
     Also, in PROGRAM #2 I use long variable names to make the program more
     readable. Naturally BASIC will only read the first two characters of
     the variable. For example the BASIC interpreter will refer to the
     variable BEGINNING as BE.
     
     I hope these hints are helpful. If they are, pass them on!
