Adam Dunkels, well-known author of the Contiki operating system and the uIP embedded TCP/IP stack, has written a really small BASIC interpreter called uBASIC in about 700 lines of C code. It is intended to be a very small scripting language for systems where memory really is at a premium such as deeply embedded systems which may have as little as a few hundreds of bytes of RAM. It provides an interesting look into how to write a very lightweight script interpreter.

My eyes! They burn! Never understood what drove people to submit programs to the IOCCC. Must be have some sadistic streak in them. 
The code posted in the original article reminds me of the C interpreter I wrote during my undergraduate years. It's simple, it's straight forward, though I imagine BASIC is an easier language to parse than C since you have less overloaded constructs (the operator * for example).

I use the 25 line dds.c - http://www.ioccc.org/1990/dds.c - from the 1990 ioccc competition for all my BASIC needs.
Also: 'a very small scripting language for systems where memory really is at a premium'. Didn't some guys called Gates and Allen do something similar a few years back?
