Comments inside ASM blocks (*solved*) - einar - 2013-08-20

Trying to compile the sub-routine below...

Code:
sub test()
    asm
        ex af,af'               ; A'=player
    end asm
end sub

...produces this error message:

Quote:C:\...\zxbasic-1.3.0s1022\dist>zxb test.bas
test.bas:4: Error: illegal preprocessor character '='

However the following sub-routine compiles just fine:

Code:
sub test()
    asm
        ex af,af'               ; A=player
    end asm
end sub

This other sub-routine also compiles just fine:

Code:
sub test()
    asm
        exx                     ; A'=player
    end asm
end sub

ZX BASIC parser is obviously misunderstanding those two apostrophes in the first case.

This is, again, another corner case for the ZXBASIC preprocessor when entering an ASM context. A' is also a register (hence the confusion). Let me check it...
