As suggested by https://github.com/rednex/rgbds/issues/350#issuecomment-498030458
The order `count` then `byte` was decided after some discussion:
- First argument consistent with single-arg syntax
- Intuitive at least to some people other than myself
- Consistent with other assemblers, at least ca65
This adds two new directives: newcharmap and setcharmap.
newcharmap creates a new charmap and switches to it.
setcharmap switches to an existing charmap.
Should partially cover #178 and close#270.
This allows printing numbers in different bases and without the dollar prefix
This is especially useful in macros because the dollar isnt a valid character
for symbol names, requiring heavy `STRSUB` usage.
The original list only existed because the documentation was split
across multiple files. When all keywords are described in a single
document, Ctrl+F suffices to find them.
rgbasm tries to optimize any loads from/to $FF00-$FFFF and generate
LDH 2-byte opcodes instead of regular LD 3-byte opcodes. This is a bit
inconsistent as it only works for constant values. If a load is trying
to access a label in a HRAM floating section, or a section found in a
different object file, this optimization doesn't work.
This means that a simple refactor or code could allow rgbasm to perform
the optimzation or prevent it from doing so. For certain projects, like
disassemblies, this is a problem.
This patch adds flag -L to rgbasm to disable the optimization, and
doesn't change the behaviour of any other existing code.

Newlines have to be handled before comments or comments won't be able to
handle line endings that don't include at least one LF character.
Also, document an obscure comment syntax: Anything that follows a '*'
placed at the start of a line is also a comment until the end of the
line.

PRINTV prints integers in hexadecimal, PRINTI prints them in signed
decimal. For example:
PRINTT "Error at line "
PRINTI __LINE__
PRINTT "\n"
