[Simh] 101 Basic Games for RSTS/E (was Re: PDP11 on Simh for public access)

[khandy21yo]

Rsts basic+ has two modes. Extend and noextend,
Noextend is the original mode, where 'line continues with a linseed and ends with a return. The & character works as a shortcut for print. Statements were separated with a colon :
Extend mode was changed things around. It was a later addition. 'line continues used the &, statement separator was the /, and shortcuts were gone.
Put a line at the front of the code like '1 noextend and they may work fine as is.

I'm pretty sure Ahl was in Education System's group, which I thought at one point was in MRO (Marlboro).    Small-systems was in the Mill.  MRO was 36-bit land.   So he would have had access to the 10s, but I note you're right there had been many 8s in the Education stream.
That said, few HSs could even afford them.  Folks in HS's  (like my father who was teaching Math in a HS outside of Philadelphia during that time period) were most likely running on remote timesharing systems via dial-up lines - with GE(Honywell)/Mark-IV being the giant in that business (my own entry in the computers with him in '67 was on the Mark-II and Mark-III).   DEC's customers that were trying to get into that business were mostly supported by PDP-10s, not small systems.
RSTS Basic is a late entry, the language support for it, originally came from the compiler group which again was originally PDP-10 based (also remember the PDP-11 BLISS compiler needed a 10 to run it).
I can not look in my own archives from the time, my only PDP-10 documentation I have left from the early 70s, is the white monitor 'phone book.'  I do have later (circa '78) PDP-10/20 docs but that would have be after the book described was published.
