Last time I looked, both QB64 and FreeBasic were pretty good and had active forums and wikis etc

Both are nice implementations of QuickBasic for a number of platforms

I know it from back then and it can do some pretty impressive things. Not sure how I’d start from scratch these days but it’ll definitely be out there.

10 PRINT “AM I BASIC?”

20 INPUT N$

30 IF UCASE(N$) = “YES” THEN PRINT “CORRECT” : END

40 GOTO 10
