Indeed Dave, that's what I meant, I will correct the typo.

Good catch! For my part I thought I didn't have Vol.2&3 but I finally found all volumes (3+3 ? ) and what a good surprise to see more details on same topic. There is other useful related information. I'm particularly curious about the process the OS uses to properly remove ROMs or IRAMs with Lex files because I have sometimes big memory losses when removing with just POKE”2C0xx”,”00” OFF/ON even with the last connected Fram Block and that's not just a Memory Lost but IRAMs Fram blocks that turn into RAM... The computer freezes with the poke in the screen. Last time was with the workbook71, the SC Forth-Assembler is particularly sensitive too.
Any ideas about that ?
