Well, I'm open for questions. My only problem is I'm so swamped that my
turnaround time is frequently abysmal...
Do you know how many sections the SC40 supports? The KL supports 32.
The reason I'm asking is because supporting DECnet in Kermit turned out
to be a far bigger job than I ever expected and my section zero virtual
address space started feeling a little cramped due to all the .PSECT's
I'm using.
What I did was move all the program help and text into section 1, viz:
@g kermit
@i mem
152. pages, Entry vector loc 614522 len 3
Section 0 R, W, E, Private
2 KERMIT.EXE.2559 1 R, E
6 KERMIT.EXE.2559 2 R, E
10 KERMIT.EXE.2559 3 R, E
11 KERMIT.EXE.2559 4 R, CW, E
20 KERMIT.EXE.2559 5 R, E
30 KERMIT.EXE.2559 6 R, E
35-36 KERMIT.EXE.2559 7-10 R, CW, E
42 KERMIT.EXE.2559 11 R, CW, E
100-101 KERMIT.EXE.2559 12-13 R, CW, E
103-104 KERMIT.EXE.2559 14-15 R, CW, E
106 KERMIT.EXE.2559 16 R, CW, E
500-615 KERMIT.EXE.2559 17-134 R, E
Section 1 R, W, E, Private
1001-1055 KERMIT.EXE.2559 135-211 R, E
1300-1315 KERMIT.EXE.2559 212-227 R, E
1500 KERMIT.EXE.2559 230 R, E
So that's 60. pages in section one. One doesn't want to 'bump' into
things... I also have guard pages to catch those pesky off-by-one errors.

Well, we'll do the best we can, and I'll learn those limitations. I
myself was never a PDP-10 guy; I cut my teeth on PDP-8, PDP-11, and
VAX systems. I'm slowly learning TOPS-20 on the SC-40 so we can open
it up for giving accounts to people here. (and elsewhere)
