Hello, Picnic. Is there a way to run it on GNU+Linux without wine/emulation? Windows is kinda dated by now, people are switching away from it.

Wow! It looks great!
But why the 58,5 KB program running tiny examples uses 397 MB of memory? 
Could you reduce it to 39,7 MB or, even better, to 3,97 MB? My system is Windows 7 x64 SP1. |

It plays great too, I've tested it on different versions of Windows.
Thanks for the feedback 386 I can definitely reduce it to have very low startup requirements. Anyway, I uploaded a new version. The memory footprint should be should be around 30 MB now. Last edited by Picnic on 15 Nov 2023, 22:48; edited 4 times in total |

Thanks, Picnic! 30 MB is much better than 397 MB!
Just curious: is it possible to make 3 MB or 300 KB? |

Hobby BASIC uses one main internal structure for all data types, 88 bytes in size.
This practically means that, for example, every 1 mb of memory I allocate, I get about 12000 elements (strings, variables, arrays, labels, etc.) More than enough for a simple toy interpreter. But maybe I should let the user decide the size of memory they want to use. I changed a few values in memory allocation calls at startup. That's all.

It's easy to implement, i'll think about that. Thanks again for your feedback 386. Quite useful !
