#printm - a modular micro printf replacement for 65C02

Here is a modular micro replacement: printm()

• Literals have the high byte set (APPLE text)

• Meta characters have the high bit cleared (ASCII)

  $ Hex - print 2 Byte x Hex - print 4 Byte

  @ Ptr - print hex byte at 16-bit pointer & Ptr - print hex word at 16-bit pointer

  Dec - Print 1 Byte in decimal (max 2 digits)

  d Dec - Print 2 Byte in decimal (max 3 digits) u Dec - Print 2 Byte in decimal (max 5 digits) b Dec - Print signed byte in decimal

  % Bin - Print 8 bits ? Bin - Print 8 bits but 1's in inverse

  o Oct - Print 1 Byte in octal (max 3 digits) O Oct - Print 2 Byte in octal (max 6 digits)

  a Str - APPLE text (high bit set), last char is ASCII s Str - C string, zero terminated p Str - Pascal string, first character is string length

Each option can individually be enabled / disabled to control the memory footprint since you probably don't need "every" feature. Seriously, when was the last time you needed octal? :-)

printm() has manually been optimized for size. In gcc parlance, -Os. With everything enabled printm() takes up less then 512 bytes.

See the latest code for the exact byte usage!
