/* Version 15
printm - a printf replacement for 65C02
Michael Pohoreski
Problem:
Ideally we want to print a single line that includes literal and variables
in MIXED ASCII case -- high bit characters would be output "as is"
and ASCII characters would be interpreted as a variable output.
While originally this gives us a nice 1:1 mapping for input:output ...
.byte "X=## Y=### $=####:@@ %%%%%%%%~????????"
... it has 2 problems:
a) it has to be constructed in pieces
b) and it is bloated.
Is there we can use a more compact printf-style format string
where we don't waste storing the escape character, and
toggle the high bit on characters on/off as needed?
Yes, if we use a macro!
PRINTM "X=%# Y=%d $=%x:%@ %%~%?"
Thisis why printf() on the 6502 sucks:
- is bloated by using a meta-character '%' instead of the high bit
- doesn't provide a standard way to print binary *facepalm*
- doesn't provide a standard way to print a deferenced pointer
- 2 digit, 3 digit and 5 digit decimals requiring wasting "width" characters
e.g. %2d, %3d, %5d
When a single character would work instead.
Solution:
Here is a micro replacement, printm()
* Literals have the high byte set (APPLE text)
* Meta characters have the high bit cleared (ASCII)
x Hex - print 2 Byte
$ 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
% Bin 1 Byte
? Bin 1 Byte but 1's are printed in inverse
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
Note: The dummy address $C0DE is to force the assembler
to generate a 16-bit address instead of optimizing a ZP operand
The printm with everything enabled takes up 472 bytes
