Force Absolute Addressing not working

[dwsJason]

In 65816 mode, forcing absolute addressing doesn't work.

Input source: lda.z $101030 // .z zero page lda.a $101030 // .a force absolute lda.l $30 // .l force long

---- output on the listing $0004 a5 30 lda $30 3+2 lda.z $101030 // .z zero page $0006 af 30 10 10 lda $101030 5+ lda.a $101030 // .a force absolute $000a af 30 00 00 lda $000030 5+ lda.l $30 // .l force long

As an aside, the WDC standard for forcing these modes would be lda <$30 ; Force Direct/ Zero page lda |$30 ; Force Absolute lda >$30 ; Force Long

I really like your assembler.

Thanks for looking at my assembler! I don't use 65816 a lot so not surprised I overlooked this, a fix for force absolute has been added.

I've looked at the WDC standard a bit but have a hard time reading it so I haven't considered adding it, < and > are commonly used for low and high byte of a value in 6502 assemblers and it might be hard to distinguish unless I add a command line option for WDC and disable common use of < and >. I'll consider it a 100% vote for supporting it from my known users though :)

Wow, thanks so much for fixing the force absolute! If you're data bank is not zero, or your direct page is not at zero, $0030, and $30 would be completely different memory addresses. So when using 816, I find it best to force addressing in most scenarios. I will test it out after work tonight.

For the <, |, and > address modifiers. Maybe it would be possible without impacting the other uses of <, >, and ^. Since in the former, you are modifying the addressing mode, and in the latter you are dealing with an immediate value.

With that said, you know your code far better than anyone else. It is a request to add support for it, but not a request to add a command-line switch, or remove support for the other use cases.

I have to warn you, if you keep fixing things like this, I will end up writing something large in your assembler. And that might lead to more reports.

Thank you again!

Confirm fixed, forcing absolute works!
