I'm still liking Visual BASIC 6.0 before the Dotnet era. A shame that newer versions of Windows have problems installing it. There is Jabaco that takes VB 6.0 syntax and compiles it to Java bytecode: http://www.jabaco.org/ It doesn't have ADO database support so I can't write apps with Databases in VB 6.0 and port them to Jabaco. This trying to make C++ do BASIC commands is hard, might as well use this instead: http:…

I remember of "on error resume next".

I also made ActiveX. It was a very good IDE.

I did something similar in C but I called it HereC. I mostly just did #define begin { and #define end } the other thing I did was make && to AND and || to OR was fun for a few minutes, then I never went back to it.

If you'd like to fool around with an Applesoft BASIC compatible interpreter that comes with almost 1000 listings, check out DiscoRunner http://discorunner.com

That's wonderful/abusive. There used to be a macro assembler for the Apple ][ that came with an add-on package of macros that provided a BASIC-like language. It was heavily advertised in Nibble Magazine.

It seems someone managed to dig it up, collect some recollections by the author and demo it a few years ago:

Circle is complete.

Here's a version in Haskell implemented using a monadic DSL: http://augustss.blogspot.in/2009/02/more-basic-not-that-anyb...

Also, here's ASM embedded in Haskell: http://wall.org/~lewis/2013/10/15/asm-monad.html

templates are a inappropriate macro language. Everyone knows this except the C++ aficionados.

Basic.hpp defines LET as:

    #define LET double [1]

Perhaps this would allow for a broader range of types, seen as C++11 is being used:

    #define LET auto

But part of that was already done for you in iso646.h!

IIRC, Common Lisp has something like this:

    (tagbody
        10 (print "Hello")
        20 (go 10))
