Hi Everyone,

I am looking at my quick reference guide and the basic-plus manual, I can't seem to find a way to append new information to a file.

Do I have to open the original file and read each line and print them to a new file, then print the info I want to add?

there is no:
1000 open "file.txt" for append as file #3
1010 print #3, n1$
1020 close #3

BTW how can I find out if I have basic-plus or basic-plus-2?

I think you need to use the MODE keyword with an appropriate value.

The BASIC+ manual just mentions the MODE keyword, but refers to the
RSTS/E programming manual for more details. So you need to go and dig in
there. Bit 1, I think. But test around some, and read the docs...

For BASIC+2, you say:

OPEN "file.txt" ACCESS APPEND AS FILE 3

BTW how can I find out if I have basic-plus or basic-plus-2?

If you are switching, then it is into BASIC+.

BASIC+2 you need to run. And it's also easy to tell when it starts:

.bp2

PDP-11 BASIC-PLUS-2 V2.7-C

BASIC2

BP2 complains about that syntax. I will see if I can hunt up a Basic-Plus-2 manual .pdf file.

BP2 also hated my compound statements: "1000 n=0:l=0:m=5:q=7 "

But at least I have Basic+2 which is nice.

You can find that manual too on Mim.

And yeah, I messed up.

It should be:

OPEN "file.txt" AS FILE 3, ACCESS APPEND

BP2 also hated my compound statements: "1000 n=0:l=0:m=5:q=7 "

: for separating statements was already deprecated in BASIC+, but still possible. Not allowed anymore in BASIC+2. DEC changed into using
backslash. So if you do:

1000 n=0\l=0\1=7

it should work.

Also, BASIC+2 do not need line numbers. But for that, you need to edit
the file outside of the BP2 environment, and load the file. You can also
have labels where you think they might be useful instead of line numbers...

But at least I have Basic+2 which is nice.

Ok. That's good.

It does. Oh, and if you want a bit of inspiration:

http://mim.stupi.net/sources/

(that's the sources for the web server giving you those pages. All
written in BASIC+2.)

Hi Johnny and everyone,

I am looking in on-line help and in the "Basic Plus 2 RSTS/E User's guide" but I don't see how one might do this:

from a DCL prompt launch BP2 with a basic program in a .B2S file and run the Basic program.

I can launch BP2 then I have to manually OLD <MYFILE> The .B2S extension seems to be optional, then RUN.

BASIC+2 is primarily a compiler. You compile your program, and get a
.OBJ file, which you then link, and then you have an executable.

See the help for COMPILE and BUILD in BASIC+2.

With that said, if you want to run something interactively, I would
think *maybe* this would do it:

$ BP2
OLD FOO
RUN

But that is a guess from my side. I'm no expert in RSTS/E... I can tell
you how to do it in RSX, but that won't help you. ;-)

I was playing with that earlier - the build step looks like TKB, but I could not get the correct incantation to turn my .OBJ into a .TSK -- This is what I want to end up with, right?

I will try the compile and build commands from within Basic+2.

The BUILD command will create the command file needed for TKB to link
the file.

Once you've createed that command file for TKB, you use that.
In RSX, the command would be

TKB @file
(in MCR)

or

LINK file/BASIC
(in DCL)

Not sure how it might be invoked in RSTS/E...


The exact settings used for generating that input can be seen if you do
"SHOW" in BP2.

This has it - for the Basic program COLATZ.B2S
BP2 COLATZ
LINK COLATZ
RUN COLATZ

Will compile link and run the program, leaving the intermediate files in the directory.
