Oh, while I'm thinking of it: maybe consider changing the docs redirect to the 2.x branch on pc-basic.org by default?

Thanks for your awesome work here, Rob! I was curious about the 1.2 — I've exclusively used 2.x and wondered about the dual status.

This other 'Post' window just popped up -- I just clicked 'Cancel' but all it does is delete the text in the window!

Thanks much, Mark, for the reply -- If I remember correctly, back in the day, you could enter "LLIST" while in the program and it would send a listing to the printer. I'm pretty sure I tried your sugg. recently - (LLIST then exit) , but it still didn't print for some reason, although I just tried again, and it did print after exiting -- so thanks for that tip; I guess that's all I needed to know, although it would be nice to be able to 'LLIST' from within the program. Gary

Marc 'BlackJack' Rintsch posted a comment on discussion General Discussion
What does „couldn't LLIST“ mean exactly? Have you tried giving an explicit printer name in the options? For me the actual printing is triggered when I close PC-BASIC. The Z: directory in PC-BASIC is the current working directory the program is started from/with. So if you start it from the command line, then you should navigate to where you want to load/save data from. If all you want is converting a BAS file from tokenized form to a text file, there is the --convert option.

Is anyone there ??

Still looking for a reply -- If there's any there, pls let me know where to look ( garyd52013@gmail.com) Thanks

Greetings -- I tried using suggestions in a couple of related issues, but had no luck. On my desktop computer (wired to printer) there was no .ini file to be found, and on the laptop, I found a file and enabled "lpt1=printer:" but still couldn't 'LLIST' I can't even figure out a 'workaround' (saving to a file) being trapped in this phantom Z directory! (Tried " SAVE "C:\file.bas" but not found. Is there a way to 'Save As'?) Can anyone help?

Hi, first many Thanks for PC-BASIC! I would like to ask if there is a chance that there will be a Non-SDL version of PC-Basic for Windows in the Future? I would start it (in the past) like GWBASIC.EXE from the SHELL/CONSOLE in Windows Many Thanks for the answer in advance :)

Hi, I just wanted to share with the pcbasic community two ways to delete a line or part of it I just used in a program of mine. the goal is to have a subroutine you can use in multiple position around your program just passing to it two variables: Y the line you want to delete and X the point where you want to start deleting. The only drawback is that you can delete only from a point to the end of line, not let's say ten characters at the center of a line. this code uses a for cycle to locate a fixxed...

Hi, Due to limitations in the compiler, I had to tweak the code in order to compile it. This is the final code I compiled. However I am afraid I broke the math in line 10 when inserting parenthesis for RND(). The compiler is unable to parse RNDnumber, it requires RND(number). I think I might have mistranslated RNDG/2, RNDEV250, and PERC=RA100/(G+0.1).

I've been using PC Basic for the past few years to run a program that I wrote for a college football pool. Last year, since there was no college football, I never had to use the program but when I attempted to run PC Basic on my mac today, all I get is a window with no prompts. I don't even know where to start to resolve the issue. Has anyone else experienced this kind of a situation?

Thanks for checking, not sure what could cause the lag. Regarding the memory management - thanks for reporting, it's more or less expected that 1.2 performs differently. One of the big changes in the 2.0 branch is the way arrays and (in particular) strings are handled, in order to follow the behaviour of the original more closely. It's far from perfect though, some parts of how the memory allocation behaves in GW-BASIC I just haven't been able to understand so far.
-
Thanks Rob for your reply, much appreciated and clear. I tried your suggestion and used python 3.9; even if the program seemed to run a bit faster, there was a sort of lag. Something that should do with the way 3.9 handle the timings. Didn't tried pypy but if ctypes doesn't cause issues, integrate pypy libs into the windows package should help the project, I would say. I also noticed different memory management between 2.0 and 1.2. Same 600 lines/50KB program, with FRE(1) command, after RUN and CTRL-C...
-
There shouldn't be a backslash between FILE: and the drive letter

Great tip, thanks! Did everything work or are there gaps? I seem to recall there used to be issues with ctypes under PyPy, but that was a while ago...
-
FWIW, though I didn't benchmark things, I've had good results using PyPy (https://www.pypy.org/) to run PC-BASIC with great speedups. Might be worth a shot depending upon needs.

Hi .Rob Hagemans I tried to make the print commands come out as text, but it didn't work. Is there an error entering the file path? lpt1=FILE:\D:\Program\Engineering programs\MASS\Print I hope that you can guide me in the correct way to modify it for printing in text form, or please modify the file and re-publish it here
-
Actually, numpy is quite well optimized, and faster if you have the sort of task it is meant for - i.e. vectorised calculations. I removed it not so much for performance but to get rid of a large dependency (it was steadily ballooning and added something like 10 MiB to the package) and for maintainability - I want the basic functionality to be available using the python standard library only, but that meant having to maintain separate code for numpy and non-numpy installs and it was just not doable...
-
2.0.x uses Python 2.7 if you install it for 2.7. Just install it for Python 3.
-
I know pygame and numpy are well known for their slowness (even if they have tricks to make some optimizations), so I would have expected the speed difference to be the opposite between the two branches, now I know why, thanks. I even noticed you compiled every .py files into pyc, that should make a slight speed increase, I do not know how much noticable is in a so complex program like yours (complexity that never stops to amazes me, sincerely). Could you enlight me on what circular dependencies...

If neither option does what you are looking for, then I am afraid I have run out of ideas and am unable to help you any further. Perhaps someone else on this forum might be able to. Best of luck

What are the steps to modify to line,page
-
No, it's not possible for me to connect to your device. You're set up to trigger print for every page break. That means when a page break character is encountered, the page will be printed; anything left at the end will be printed on closing PC-BASIC. If you want every line to be printed separately, use print-trigger=line. Your write that you want to print "every command sent" - unfortunately there is no such option, the options are line, page, or close. If none of these do what you need then unfortunately...

We connect devices through anydesk . Please agree to resolve the issue with respect

Is it possible for you to contact my device and take the steps to solve the printing problem when closing the program and make it print after every page

I made the modification as in the attached picture. Is what I did right... When closing the file, saving and running the program, nothing changed. The method did not work.

You have print-trigger=page which means it sends to the prnter after every page. If you need after every line you should set print-trigger=line. s that what you are looking to do?

I deleted the # as you can see in the attached picture, is there anything I should do as well

I want the program to print while working on it and to control the printing, not when the program is closed So try the method you mentioned, which is to go to (C:\Users\Ali ZaaZaa\AppData\Roaming\pcbasic-1.2)... I found two files, one of them is PCBASIC.INI that I attached earlier. I opened it and modified it by removing # then closing the file after saving.. I ran the program but it didn't work, the program still prints after I close it
-
Hi, please see here for a guide to printing options: https://robhagemans.github.io/pcbasic/doc/1.2/#printing I'm not sure exactly what you want but it sounds like this option may be what you need: https://robhagemans.github.io/pcbasic/doc/1.2/#--print-trigger If it doesn't work, please state exactly what you have tried, otherwise I or others won't be able to see the problem.
-
The attached file is PCBASIC.INI. Editing should be done on it. Would you edit it for me please? I removed the # , but it did not work ... I have a program that was designed on the GW BASIC language. I want it to send every print command and to control that. I downloaded a program DOSPRN but pc basic does not send print commands
-
If you want to make a change to a line in that file, you need to uncomment it by removing the # in front. As it stands, in the file you attached, all lines are comments and have no effect.
-
Hi, thanks for your message. It's true that the 2.x branch is slower. The 1.x branch had become unmaintainable due to circular dependencies, in order to disentangle the code I have made large changes to the structure, including the use of threading to separate interface and engine. Unfortunately the code is not as highly optimised as the 1.x branch was.
-
Thanks for the report, added to th bug tracker here: https://github.com/robhagemans/pcbasic/issues/139
-
I need to modify the printing that prints every command sent and not when the program is closed. When modifying an PCBASIC.INI file, nothing changes. I do not know the correct modification steps need help
-
I can confirm this and that GW-BASIC doesn't do this. The program just ends there. Maybe this would be better a bug report over at the Github repository: https://github.com/robhagemans/pcbasic/issues
-
I'd like to know the technical details. I already read about deprecated libraries like pygame. The fact is that 1.2.14 is far faster then 2.0 branch. As example, paste a 60KB program into 1.2 happens almost instantly, in 2.0 it takes one minute or so. It is neither an issue nor a complaint, I use both versions depending on needs, just curious. Keep up the good work regards Stefano

Under Linux, regardless of the hardware platform, I'm using pip to install PC-BASIC. Make sure you use the pip for Python 3. That's pip3 on some Linux distros. Or even better, use the Python 3 you want to install it for to run the pip module of that very Python installation, e.g. python3.6 -m pip install pcbasic.

Tom Lake posted a comment on discussion General Discussion
Compaq BASIC was an exact clone of IBM BASICA. KEY(30) was F11 and KEY(31) was F12 in the KEY(n) and ON KEY(n) statements. If n was 15-25 then you could trap other keys by CHR$(KBflag)+CHR$(scan code). KBflag is: Caps Lock Inactive = &H0 Caps Lock Active = &H40 Num Lock Inactive = &H0 Num Lock Active = &H20 Alt = &H08 Ctrl = &H04 Left Shift = &H02 Right Shift = &H01 Duplicate Key = &H80 Scan code is the usual scan code of the keys on the keyboard.
-
Hi Tom, that's interesting! At the moment F11 and F12 are only supported in Tandy mode, and even then it clashes a bit as these keys are used to access emulator functionality. I think the Compaq was a much more regular PC/AT clone. Would you know of any documentation (e.g. online links or pdfs or some such) for these versions of Compaq BASIC? I'm wondering if it has more extended features, it may be possible to include some of its features in a future version. Though admittedly I haven't had much...
-
Hi Mark, thank you very much for your interest and it's great to hear of your appreciation! You're very welcome to use/build on the emulator, currently I don't have plans to set up a donation option.
