Tiny Basic tinkering

One of the examples on the Run Basic website is a port of Tiny Basic. It's fun to play with and is very much like the interactive, command line Basics found on early personal computers. In fact, I think Tiny Basic was the dialect used on the TRS-80 Model 1.

I'm currently working on modifying Tiny Basic to run the Sieve benchmark. Tiny Basic needs two things: profiling and array support.

I've already added profiling support for the RUN command. Tiny Basic now displays the running time of a program in milliseconds.

The last step is to add array support. Tiny Basic only supports the numeric variables 'a' to 'z'. I'm adding a single array to the environment in order to port the Sieve program. The array will be called a().

I will post the modified Tiny Basic code to the Run Basic Programming Wiki when finished. The whole point of this exercise, however, is to see how fast the Tiny Basic interpreter runs the Sieve benchmark and compare it to the others in the last post.
