Hello all,
A new version of WimBasic has been released. It is available at http://wimbasic.webs.com
A new command has been added: ERASE. This deletes an array that was previously DIM'd. Useful when memory is scarce, an array needs to be reinitialized with zeros or empty strings, or needs to be redimensioned. In a single ERASE command, multiple arrays can be deleted.
Also the autostart feature is fixed. During startup, WimBasic searches for a file called WBSTART. When this file is found, it is loaded and RUN.
Regards,
Wim.

Re: 2022 version of WimBasic
Congratulations! It is great project. I trying it and I loving it.
Coincidentally I also released final and ultimate BASIC (V2) version of TRIANGULAR μOS for VIC-20 today (version 1.15/VIC).
I assume that you can only perform GOTO or GOSUB to line number stored in variable by using EXEC command?:
GOTO A => EXEC "GOTO"+STR$(A)
GOSUB A => EXEC "GOSUB"+STR$(A)

Re: 2022 version of WimBasic
Calculated GOTOs/GOSUBs are a recipe for disaster.TRIANGULAR OS wrote:I assume that you can only perform GOTO or GOSUB to line number stored in variable by using EXEC command? [...]
They do not provide any advantage beyond what is otherwise doable with the ON X GOTO/GOSUB statement, unless one happens to have a group of jump targets that follow an arithmetic progression, so something like "GOTO 10000+X*1000" could be applied for space savings. In the latter case, a simple RENUMBER that was intended to straighten the line numbers - during or at the end of development - will render that GOTO statement non-functional.

Re: 2022 version of WimBasic
Mike you're right. Although it will be sometimes great to have possibility to GOTO or GOSUB into some function by using a variable, renumber will totally disable code. I will only work if one keeps its subroutines pack tightly in the begging of program, so they won't be renumbered (if we keep same renumber parameters). Otherwise something like labels and branching to them would have to be implemented in language.

Re: 2022 version of WimBasic
Mike's comment is completely correct, so I would go for that.
To answer your question: In WimBasic an EXEC "GOTO"+STR$(A) works as intended should you choose to use a computed GOTO.
EXEC "GOSUB"+STR$(A) may run into problems in some scenarios because of the GOSUB stack frame interfering with the EXEC command.
I have not tested that thoroughly (as I mentioned in the documentation).
EXEC is very useful for DOS commands e.g. EXEC">S:FILE" to scratch a file
Regards,
Wim.

Re: 2022 version of WimBasic
I used an MCes Jolly Cartridge PCB to make a WimBasic+8K physical cartridge
Why 8K? I have some free HM6264s sitting around from a picking error. Apparently it wasn't worth the vendor's time to have them sent back. And they need homes
I've got a damn busy week ahead at work, but hopefully I'll be able to squeeze in some time to play with WimBasic.

Hey chysn,
It is great to see the fruits of my efforts being used across the world!
Please let me know what you find!

Re: 2022 version of WimBasic
Right, even I'm now considering creating VIC-20 version of TRIANGULAR μOS that will work with your WimBasic. Right now I'm converting it to C64: https://www.lemon64.com/forum/viewtopic.php?t=80381 , so I will sit at this in the future.
