The detours involved to reach either the original monitor routine or the Printer Monitor during or after execution of a decimal program was mentioned at least twice in Book 3 (see chapter 12, page 151 and appendix 2). The 'detours' consisted of a few instructions stored in PIA RAM.
Although the detours are still necessary, the corresponding instructions no longer need to be entered into the PIA RAM by the operator, as they are now located in the very last section of the PM/PME EPROM. The details are shown in figures 1a and 1b - the BINAR and PMBINA routines.
