I know a Extension named small basic fun in archive may be we could find it link of codeplex archive also we should add extext,exprogram,square basic,data Extension like Extension you can search thread in man small basic forum archive on way back machine
Hi ZS,
I did do a quick look and couldn't see any active links to any dlls or source for most of these, but if you find any I am happy to try to update and host them.
Many of those you mention were quite small and were mainly tests of creating an extension rather than adding significant new functionality or widely used, but there may be some jems waiting to be rediscovered

.
Thanks for finding these, I will look into them all. I may not add all to extension manager if they don't really add anything or don't work, but all I get going I will share here.
ZS,
I do remember the Data extension having a lot of stuff in it, but it was also copywrited and the dll was obfuscated (cannot easily be decompiled). Clearly the author didn't want it tampered with, so I wouldn't. Papa Lapub did collect a lot of stuff and was very helpful maintaining LitDev xml German translation, but I haven't heard from him since demise of old MS forum.
Some of the ones you have found links for (well done again) below:
Download, unblock, unzip, copy dlls and xml to lib folder.

Maestro - some missing dlls and compiling issues - if anyone actually has this hardware I could work harder at it!

SquareBasic by Benedikt Muessig

Use Tools->Search Extensions in SB-Prime to see API for these
Enjoy

Thanks for the great effort

If anyone is interested, I found a copy of the Data extension by Oskariok. It is for version 1.0 of Small Basic and has its own installer. Both included in the zip below, along with the resulting Data.dll and Data.xml which probably work without the Data installer. You would need to uninstall SB (maybe take a copy of your current lib folder first), install SB version 1.0 and then install Data extension or copy the dll/xml to lib folder (in this version of SB you may need to create the lib folder). I have not tested, but it's there if anyone wants to have a go. As I mentioned before, the resulting dll is obfuscated and I cannot update to current SB version.
Data by Oskariok (version 1.0 SB)
Finally, if there is anything in this that is really interesting I would be happy to consider implementing something similar in LitDev extension if it fits into the ethos of complementing and working fully with standard Small Basic. I probably didn't at the time since I didn't want to copy other extension ideas, but since clearly it is not maintained I would be happy to now.
EDIT
It is possible to extract a Small Basic version from its msi without uninstalling/installing so you can have multiple versions (msi is just a zip). This means you can easily test an old version and you can switch between versions (including sVB) in SB-Prime using
Advanced->Options->Small Basic Installation Path, or just use the different versions of SB.exe.
Below is a zip where I have done this with SB_v1.0 and test the Data extension.
SB1.0
Data Extension Is Working In SB 1.0

But Other Extension You Have Updated No One Is Working.
If Anyone Has Same Problem Please Reply.
I just tested the first of these by downloading. Remember all apart from Data are for SB version 1.2 ONLY. Remember for unblock downloaded zip.
This is my test code, note the extension is in the same object name "Text" for ExText4SmallBasic.
Code:
a = Text.Split("hello world"," ")
TextWindow.WriteLine(a)
