What binary format did QuickBasic use for BAS files?

Question

I found some very old floppy disks. I sent them to a company to restore the files and they were still retrievable!

Next to old games and simcity save games I found some .BAS files.

Some of the names I recognize from the first games I made in my life, but the files look scrambled or compiled or something.

One of these files is i.e. this one (gzipped and base64):

begin-base64 644 ramlem.bas.gz

If I remember it is an animated mix between a Rambo and a Lemming. When I open this file in Notepad++ I see something that LOOKS compiled or compressed or something.

I remember that I programmed first in QBASIC, but after a while in QuickBasic that had some more PRO features. Could it be that QuickBasic compressed files on save?

The files seem to be more then 30 years old. Of course I would love to see the original source or get it running!

Does anyone have a gut feeling what I am looking at and how I could get the original source code or run the file?

Downvoted because having to download a file to look at the text that you want us to identify... isn't going to happen. — dave, Commented Nov 9, 2023 at 3:57
It’s not a text file. Although after gzipping it could fit in 60 lines of base64… — user3840170, Commented Nov 9, 2023 at 7:52
@another-dave it's a partly binary file, so it would not render in markdown properly. That's why I included a screenshot so maybe people could figure out by looking at that if they (understandably) didn't want to download the file. Bit more love man, you clearly help a lot of people - why also the negative part? — Dirk Boer, Commented Nov 9, 2023 at 10:53
In case it makes it easier to recognize, the first 16 bytes of the unzipped file are FC 00 01 00 0C 00 81 01 82 01 06 00 01 02 03 04. — dan04, Commented Nov 9, 2023 at 15:10

They seemed to be QuickBasic 4.5 files. A proprietary format from QuickBasic that was not only a text file, but included various other concepts like Subs - that were sort of sections into the file.

So the conclusion is; they are partly binary files that can only be read by QuickBasic 4.5.

I found the following site for a combination with DOSbox and QuickBasic to load the specific files.

https://www.qbasic.net/en/qbasic-downloads/DOS/Windows-Solutions.htm

I you also try to run old QuickBasic files and come across problems with mouse interfaces I recommended reading this answer: https://retrocomputing.stackexchange.com/a/28021/27410

Isn’t “sub” just BASIC jargon for a subroutine? How is it specific to that binary format?

@user3840170 It isn't specific to that format. It's not a text file, its tokenized. Which was quite common for early BASIC ”source” code.

@BlackJack: Indeed. There was an option to SAVE or LIST programs as ASCII text, but every line-numbered BASIC interpreter I worked with stored .BAS files in binary tokenized format by default.

QB64 detects it as a QuickBasic 4.5 file, tries to convert it, and fails on my system. That's probably fixable. That would let you try it on a modern system

The example can be loaded into a copy of QuickBasic and then saved as a plain text file:
