2c7ccca210 Added the optional C keyword "volatile" to the __asm__ statement grammar. 
It prevents the statement's Assembly code from being optimized (e.g., moved or removed).  Optimization is disabled for that statement's entire function (other functions aren't affected).

8b685763d4 Renamed chrcvt to chrcvt65 and added it to the build. 
The /Makefile presumes that all binaries are are named *65 so chrcvt had to be renamed in order to be added to the build.

e2419ece0b Added scrcode macro for the Apple II. 
Although the Apple II generally works with plain ASCII (i.e. in the ProDOS 8 MLI) the actual screen codes differ. This fixes #260.

d8c31cf1d3 Renamed RAM to MAIN for all disk based targets. 
The name RAM doesn't make much sense in general for a memeory area because i.e. the zero page is for sure RAM but is not part of the memory area named RAM.

For disk based targets it makes sense to put the disk file more into focus and here MAIN means the main part of the file - in contrast to some header.

Only for ROM based targets the name RAM is kept as it makes sense to focus on the difference between RAM and ROM.

419eb700b5 Renamed INITBSS to INIT and INIT to ONCE. 
The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name.

Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.

67cd0c2197 Added .asize and .isize pseudo variables 
These pseudo variables will return the size of the accumulator/index
in bits.

For the 65816 instruction set .ASIZE/.ISIZE will return either 8 or 16,
depending on the current size of the operand in immediate addressing
mode.

For all other CPU instruction sets, .ASIZE/.ISIZE will always return 8.

For example:

	; Reverse Subtract with Accumulator
	; A = memory - A
	.macro rsb param
		.if .asize = 8
			eor	#$ff
		.else
			eor	#$ffff
		.endif
		sec
		adc	param
	.endmacro

09e50d433d * Changed the way that Atmos programs are started. 
- Put a BASIC-language stub at the beginning.
  - Removed the Autostart flag.

  Those changes make it easy to give command-line arguments to a program.

* Made the Atmos configure file accept a special symbol definition on ld65's command line.  We can use "__RAMEND__" to increase the amount of RAM that's available to programs.

2c975d3642 Create static drivers directly from source files. 
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').
