Hallo Spiro, > *Without* the hash? OOPS! I now see what you mean; yes, there should be an hash as well! I'm really getting old :( Hallo Anders, > On the other hand those operators almost make the # implied. That thought ran across my mind as well. The only reason I can think of is that omiting # will confuse a lot of people because they are used to it. > Can the 65816 load 16-bit values to the accumulator as > well as 8-bit values? Yep. > > = high 8-bits of any address I disagree. A lot of people are used to use it for selecting the upper 8 bits of a word in 6502 mode (this notation is used by other assemblers as well!). Compiling a 6502 source in 65816 mode will result in the fact that all > operands will become $00 because the upper 8 bits of an $xxxx address will always be $00. > << = low 16-bits of a 24-bit address I my self already use '@'. '>>' isn't a bad idea but using only one character means I can use the same routine for <, > and @. An extra character means extra parsing etc. etc. Yes, I know, I'm a lousy programmer :) > >> = high 16-bits of a 24-bit address I have given this a long thought. My only objection so far: there is no 65816 register that can make use of this; you fill it either with the lower 16 bits, middle 8 bits or upper 8 bits. Not the upper 16 bits. > Add to that the operator to speficy if a given address should > be stored as 8, 16 or 24 bits when it can't be determined. I think I do not understand what you mean, please explain. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
