A tiny BASIC interpreter with C sourcecode.

Cute, but not very useful.   Posted by: BASIC Friend on Monday, October 29, 2001

Take a look at it. It's fun to play with.

found what I was looking for   Posted on Saturday, March 16, 2002

one can rarely find interpreter documentation these days...

very good for teaching   Posted on Thursday, August 21, 2003

Okay, that´s a good start. You need to go back and restructur some of the code in order to append it properly. Thanks for the upload anyways.

Superb piece of instructional code   Posted on Monday, August 30, 2004

An excellent mini-interpreter; perfect starting point from which to learn and extend.

Works nicely   Posted by: Z_Man on Wednesday, July 20, 2005

Works nicely on CRLF files, but on Unix's LF files it has problems. But I fixed that... heheh

Compiles and runs test programs flawlessly on
Linux. Great starting point for developing
a multi-platform, specialized interpreter of your own.

Interesting...   Posted by: Dominick on Saturday, December 23, 2006

how everyone commends this file for it's edifying influence, but when I keep looking for different people who are working with this interpreter or any one who has commented on it, no one seems to have treated it with the respect it deserves--commenting it (though the original comments make sense to a cs0 level student) and explaining all the parts nor has anyone tried to modify it--at least as far as I can see with my search.

Downloaded this yesterday. So far I've compiled it with KDevelop in linux and with MinGW in Windows 2000 and I have one failed attempt at hacking in a remark command. I also printed it out: 29 pages double-spaced or 18 pages (normally) long with no margins and a 12 pt font. Not too shabby for 800 lines of code.

Also, I cannot find the author *anywhere*. I can find what seems like the originating site, and I have plans to e-mail the web-master or whoever has an e-mail address there... But it's rather obscure as far as research into other programmer's work with it.

Easy to learn and extend.

Which version of BASIC does this origniate from?

Non of I think.
I started to modify to interpret C64 Basic v2 command set :)

Rewrote it in C++ with minor changes   Posted by: kangghee on Monday, February 23, 2009

Although not fully a CPP file, it can be compiled with GNU gpp. Very little changes have been done to the original working c file. Uploaded a copy to this site calling it BAS-INT-CPP.zip already. If it gets approved, you will be able to find it. If not, you can email me at kangghee at hotmail.com for the file.

Compiles fine with Tiny C compiler TCC on Windows XP.
Great starting point, easy to extend.

Code by Herbert Schildt   Posted by: Ubaidullah Nubar on Monday, April 20, 2009

This code is from the book "Schildt's Expert C++". According to him, he used a subset of standard BASIC as the target.

Use ScriptBasic Instead   Posted by: JRS on Sunday, August 09, 2009

ScriptBasic is a traditional Basic dialect that's cross platform, and designed from the ground up to be embeddable. It's distributed as a command line interpreter and multi-threaded web server.

I don't know what to make of this   Posted by: Hans Bezemer on Monday, November 02, 2009

On the downside, it has all the characteristics of a quick, ugly hack. I like so few possible prototype declarations as possible to I eliminated that one first. Then I founds loads of badly vectored, superfluous and even buggy (GOSUB stack!) code. Passing local variable addresses is BAD style and completely unneeded. Then I optimized it even more. On the upside: it is easy to understand, no myriad of C++ like structures, relatively small functions and consequently easy to understand and expand. A REM statement is easy: simply map it to find_eol().

It is not Tiny BASIC   Posted by: Alan on Friday, November 04, 2011

I fully appreciate the efforts of the author, was it Herbert Schildt who published it in his book, or someone else. And i find every effort to write a simple code, to be good. If 800 lines can be considered to be simple, but anyway.

So it is a nice small BASIC interpreter, but one problem with it is that it is not a Tiny BASIC interpreter. Tiny BASIC had a very precise grammar, like Tiny BASIC never had FOR...NEXT loop, had LIST and RUN statements, keywords were only in upper case, etc.

There are other open source implementations around which implement the real Tiny BASIC, and are more advanced as well so that they enable to do the things. No, ScriptBasic is not one of these because it is not Tiny BASIC either.
