I do most all of my T102 BASIC programming on the T102 itself (vintage computing), and occasionally use VirtualT to do testing where the faster clock speed is useful (heavy math or sort routines).
Although an older program from the DOS / Windows era, I use CodeWright for when I want ChromaCoding, as it does understand the syntax of a lot of languages and it can be customized for languages it didn't know about originally. What would be nice is a simple editor that has the command "syntax prompting" like Visual BASIC, to remind one of the correct order of command parameters. Regards, Peter
