Hi Chris.
I'm a starter for attending the workshop that you have proposed for on the second Saturday of this month - 12th Nov.
With regard to the problem I had with 64-Bit Libreoffice BASIC doing HEX commands I have posted it at...
https://bugs.freedesktop.org/show_bug.cgi?id=42492
Bug 42492 - BASIC HEX command on 64-bit systems not returning 16 characters on negative long integer.
cheers,
Ian.
