	State for a FOR...NEXT loop. More...
struct	ub_var_int
	An integer variable. More...
struct	ub_var_double
	A real (double) variable. More...
struct	ub_var_string
	A string variable. More...

Detailed Description

Retro Rocket BASIC interpreter.

Retro Rocket OS Project (C) Craig Edwards 2012.

Note

loosely based on uBASIC (Copyright (c) 2006, Adam Dunkels, All rights reserved).

uBASIC is far more limited than the dialect implemented here. It only allowed variables of one letter in length, and only integer variables, no PROC, FN, or additional functions, no floating point or string ops, no INPUT, just plain mathematical expressions, no ability to isolate execution into a context, and was (and in parts still is) quite badly optimised. It was what it was, a good starting off point.
