Subj: REPLY TO MSG #2779 (RANDOM FILES)

Yes and No..........
#1..the .DO files are all lumped together.  The directory which has the name
and start address and some other data is up in the "house keeping" area of RAM.
There's a program worth playing with that examines the directory and you'll
learn a lot....but!.... a basic program doesn't need to know the address, just
the file name, then you lineinput the openend file until you get the line you
want........as files (.DO oe .BA) are editted, their sizes change and
"downstream" files get pushed (not like a disk which may fragment a file and
keep track of the addresses to string it all together).  At my next session,
I'll upload a .DO copy of the directory program.
  
#2....a lot of this was answered above, except for the VARPRT query....VARPRT
points to the the end of a .BA file just run.....if a .BA program ends with
anything that would leave the screen with the "OK" prompt (terminated) then the
machine is ready to do other commands not in the program, like dead in the
water....if VARPRT was used, then instead of the "OK" prompt, the system goes
to where it's pointed (good doggy) and starts that program (assuming it's
pointing to a program.             I've got a program that uses that
too...TIMCRD.BA.......I'll see about getting that filed to you as well.
  
Until then, keep your FRE(0) clear,
