  • 6502bench .l1str opcode

    From Andrew Roughan@21:1/5 to All on Sat Sep 11 14:50:26 2021
    TW ROM does a JSR to print routine and then provides in-line vertical row, length byte and then string in high ASCII.

    6502bench has done a pretty good job determining strings in TW ROM, but
    needed a little help for a couple of sequences. I think a $0d in the code
    may have been interpreted as a CR and caused the interpretation to fail. Anyway, I don’t mind that, but I’m having trouble cleaning it up.

    Why does ‘Strings prefixed with 1 byte length’ display the string as comma separated hex bytes (see screenshot)

    I would expect a display like .str
    Why can’t I use ‘Display As’ to elect how it should be displayed?

    (Despite reading the help, I don’t understand why the operand dialog shows ‘Display As…’ Hex for a .str operand - that doesn’t make sense to me)

    (Needing to select all the data for the string had me scratching my head
    for a while after the last enquiry resulted in using Tag/hints sparingly,
    but I got there in the end)

    Thanks,
    Andrew

    That's peculiar. I can't think of a reason offhand why it would do that. Can you send me the binary and the project file? (Either e-mail direct, or attach in a .ZIP to an issue on github.) Maybe throw in the "SourceGen-settings" file for good measure.

    The UI sets the "hex" and "low" radio buttons by default. Those sections are greyed out (disabled) when you don't have one of the "simple data" buttons selected, but Windows doesn't hide the button selection when you disable a radio button set. To make
    the selection dot disappear I'd need to add an event handler to clear them when something outside "simple data" was selected, recording their values elsewhere, and then re-select them if you went back to a "simple data" format. It felt more distracting
    to have the selection popping in and out than just leaving it in place but greyed out.

    For those following along, I raised an issue https://github.com/fadden/6502bench/issues/110
    Andy kindly provided a script to work around this problem in the short
    term. Thanks Andy!
