Note that EDIT also take switches. You could do EDIT/TECO for instance.
Not that I recommend it, as TECO is not an editor for beginners...
$ pascal leaves.pas
Then, to link, it appears that I have choices, all of which appear to work:
$ link leaves,DB0:[11,36]PASEIS/LIBRARY
$ link leaves,DB0:[11,36]PASFPP/LIBRARY
$ link leaves,LB:[1,1]PASOTS/LIBRARY
$ run LEAVES
sum = 10946
I'm guessing that PASEIS uses PDP11 EIS opcode extensions (sometimes?)
and PASFPP uses PDP11 FPP opcode extensions (sometimes?). I have no idea
about PASOTS. But I'm glad my little pascal files are compiling/running!
So, it would appear that there are several libraries provided with the
PASCAL compiler. However, LB:[1,1] is normally the system directory
where "official" libraries are installed, so that's the one I would
normally expect to use. I would not be surprised if the installation of
PASCAL actually copies either PASEIS or PASFPP to LB:[1,1]PASOTS,
depending on what hardware you have on your system, so that normal users
do not have to think about it, and just gets the right library
independent of what hardware they might be running on.
