Usage:
      AIS LISTNAME/A, SIZECOL/N

      LISTNAME - name of the list to add all sizes in

      SIZECOL  - column with the size specifier ("K", "M" or "?")
                 SIZECOL is optional, and defaults to column 34.

Size:
      1016 bytes! Still below 2 disk blocks!

Requirements:
      An Amiga, stack can be as low as 1600 bytes (the
      program uses only 950 bytes of it, but the system
      can't set the stack to a lower value than 1600).

      At least 15K mem is required for proper operation.

      An Aminet index file (tested with RECENT and INDEX)
      or any other file in the same format ("K", "M" or "?"
      at column 36, size in columns 32-35, formatted as KKKK
      or M.M). ^^- Now selectable!!!
      
Memory usage:
      Two modes of operation, depending on the amount of
      available memory. Loads the whole index into memory
      if possible.

      Both modes:
          13464 bytes to display the requester at end

      Fast mode: (index size + stack + 1780 bytes)
         + 1600 bytes for the minimum stack (normally 4k)
         + 1852 bytes for the program and its data
         + a free mem block of at least the size of the index

      Slow mode: (stack + 1976 bytes)
         + 1600 bytes for the minimum stack (normally 4k)
         + 2048 bytes for the program and its data

History:

  1.4 - Added support for files up to 999M in size. Previous
	versions didn't support the size format xxM. Now the
	following size formats are supported:

	kkkkK	1234K (not used by Aminet)
	 kkkK	 123K, 12K, 3K
	 0.kM	 0.9M (not used by Aminet)
	 m.kM	 1.2M
	mm.kM   75.2M (not used by Aminet)
	 mmmM	 123M (not used by Aminet - Yet)
	  mmM	  12M
	   mM	   1M (not used by Aminet)

	Inverted history :-). Size 1016 bytes.

  1.3 - Changed default size column to 34. Released 13-Feb-96.
        Size 996 bytes.

  1.2 - Low mem bug fix, added command line option, doesn't
        count lines beginning with '|'. Released 22-Jun-95.
        A new argument that allows you to specify at which
        column the size specifier is located.
        Size 1016 bytes.

  1.1 - Rewritten in assembly language (800 times faster).
        Added version string. Released 15-Jun-95. Size:
        936 bytes :-).

  1.0 - Coded in ARexx, SLOW! Released 13-Jun-95. Size 3064
        bytes :-(.

Bugs: Doesn't support Aminet files larger than 99.9M (Aminet
      index file contains space for files up to 9.9M).

      Total size must be smaller than 429496729.5K (around
      419430M or 409G). This is smaller than the limit for
      the previously released ARexx version. When Aminet is
      close this size, I will remove this limit (and decrease
      the precision of the calculations).

      No more than 4294967295 files can be added to the total
      size (Aminet is now about 17300 files). When Aminet is
      growing towards this limit (in about 90000 years or so),
      I will fix this bug.

Speed:
      Tested with the Index file (30-May-95, 1175420 bytes,
      16508 lines). See notes for each test below.

      |---------|-------|-----------|-----------|------|---------|
      | Version | Files | Size in K | Size in M | Time | Lines/s |
      |---------|-------|-----------|-----------|------|---------|

      |---------|-------|-----------|-----------|------|---------|

      ¹) The ARexx version was tested using Edge v1.704. The window
         with the file was as small as possible, all programs that
         could use up some CPU time was disabled (screenblankers etc.)
         The timing was done with a stop watch.

      ²) Asm (F) means that there was enough memory to buffer the
         whole file. Timing done using my own hardware-banging timer
         (not released - yet). The timer's precision is around 1/50s.

      ³) Asm (S) means SIMULATED low mem situation. The program will
         probably be slower in a real low mem situation. The program
         reads the file line by line when you're almost out of mem.

      ** All tests done with an A500+, VXL-030 33MHz/FPU 25MHz, 2M CHIP,
         8M 16-bit mem, and 8M 32-bit mem (around 10.5 * A500).
