This would involve a line format like this <#optional_address>:<#optional_data> opcode operands <;optional comment> e.g. #01234:#4 sethex ; foo The addresses and data could be ignored (is there any situation where they would be useful?) Obviously lines which could not be generated by the disassembler (e.g. with labels defined on them) need not follow this format. While I'm using up net bandwidth, I'll volunteer to modify sass 2.31 (or the latest version I can get) to conform to the assembler syntax that is agreed upon. This is for people without access to (or disk space to spare for) Perl. And finally I would like to thank Andreas Gustafsson for a fine piece of software in the chip-8 interpreter. I would love to see it posted to the net - *very* few people in the UK have FTP access. Would it not be a good idea to: (1) augment chip-8 to better use the features of the HP48 (e.g. 131x64 dot screen etc.) we could call it chip-48 and retain chip-8 for using the vast library of software lying around in the ROMs of video games! (2) standardise an "assembler" syntax for the language. I'm hacking out a HP-48 hosted disassembler for chip-8 strings and will post it when I have time to finish it (if no-one beats me to it) Thanks once again to all you 48 hackers (and the HP crew) who have shared your knowledge and software with us!
