    Thanks Ethan.

    I had another look at it this morning.

    I had worked out all of what you posted... The key bit of information that confused me in the end was how the carry flag worked with the CMP...

    I have been looking at the CHRGET code you posted back in #140.

    Well done Ethan with your work so far in getting SAVEB and LOADB to work. I am sure Hugo will be eager to try this out when he wakes up :-)!

    Ethan,

    What does that LDA $EA60 do?

    I saw that in the generic code and it confused me then. It is still there!

    Doesn’t that just load a constant ($C9) from the MONITOR ROM rather than the...

    No, I don’t believe the ROM is corrupt. I believe there may be different versions of INIBAS out there, or you have to do something manually that is not in the manual.

    It is not the size that matters Mike :-)!

    I can't find any 'normal' vector that could be used to intercept the current basic token or character.

    You could also try the direct commands:

    The key difference is that SAVEB is pretty close to to the C64 code (and is much more straightforward) than the SAVE (in ASCII) which doesn’t have a C64...
