All, I love that everyone is promoting their personal preference!
Here's mine: - opcode tables: https://bixoft.nl/english/opcd00.htm - opcode lists: https://bixoft.nl/english/oplist.htm - visualised stratification: https://bixoft.nl/english/opcodes.htm They're all up to date with z17. What's more: I use macros and AREAD logic to produce all those pages (except the stratification one) from a single source member. And yes, those macros actually PUNCH the html. I'm too lazy to do all that typing myself ;-) Kind regards & happy programming!
