Now RESTARTing an interrupted batch file is all well and good, but just
how often do you need to write such long and complicated batch files?

Well, there is another use for this technique: SAVING SPACE ON .BAT FILES!

Every .BAT file you write will occupy 2,048, 4,096 or even more bytes on
your hard disk, even if the file is only 5 or ten bytes long.  This is
because DOS allocates file space in chunks of "clusters", where clusters
are either 2, 4 ... etc. sectors (512 bytes each!) long.

AT A COST (Slightly Slower BATCH File Execution), we can combine many small
batch files into one larger one, and still get the individual components
to recognize their old parameters, honor SHIFT etc.  We do this by using
the same "Restart" technique, but we are not "Restarting" at all ...

Presume we have two small batch files:

   @Echo Off
   REM FONT.BAT
   REM
   REM Simply copies a printer escape sequence, stored in %1.FNT, to
   REM the printer, followed by a list of one or more files, each of
   REM which is to be preceeded by that font string.
   REM
   IF .%1==. goto omega1
   set fs=%1
   shift
   :TOP1
      IF .%1==. goto omega1
      Echo Printing %1 Using Font: %fs
      COPY /b %fs.fnt+%1 LPT1: > nul:
      shift
      goto TOP1
   :omega1



   @Echo Off
   REM ZV.BAT
   REM
   REM Simply invokes PKUNZIP to list ZIP archives to screenm using
   REM a looping technique similar to FONT.BAT above.
   :TOP2
      if .%1==. goto OMEGA2
      pkunzip -v %1 | more
      Pause
      goto top2
   :OMEGA2

   Now, (note the careful choice of label names above to avoid duplicate
   labels ... messy, messy details eh what?), we can COMBINE these two
   small .BATs into one larger one, as follows:

   REM X.BAT
   @Echo Off
   if .%0==X goto omega
   if .%0==X.FONT goto FONT
   if .%0==X.ZV goto ZV
   goto omega
   :FONT
   REM
   REM Simply copies a printer escape sequence, stored in %1.FNT, to
   REM the printer, followed by a list of one or more files, each of
   REM which is to be preceeded by that font string.
   REM
   IF .%1==. goto omega1
   set fs=%1
   shift
   :TOP1
      IF .%1==. goto omega1
      Echo Printing %1 Using Font: %fs
      COPY /b %fs.fnt+%1 LPT1: > nul:
      shift
      goto TOP1
   :omega1
   goto omega
   :ZV
   REM
   REM Simply invokes PKUNZIP to list ZIP archives to screenm using
   REM a looping technique similar to FONT.BAT above.
   :TOP2
      if .%1==. goto OMEGA2
      pkunzip -v %1 | more
      Pause
      goto top2
   :OMEGA2
   goto omega
   :omega
