# tcbasic

tcbasic is a small [BASIC](http://en.wikipedia.org/wiki/BASIC) Interpreter

written in [C](http://en.wikipedia.org/wiki/C_%28programming_language%29).

## Current Status

The "basics" are done and working. The interpreter implements the

[Tiny BASIC](http://en.wikipedia.org/wiki/Tiny_BASIC) dialect of BASIC

with added support for floating point numbers and many of the built-in mathematical

functions in [Dartmouth BASIC](http://en.wikipedia.org/wiki/Dartmouth_BASIC).

Development will continue with the goal of implementing successively more

complete dialects of BASIC.

## Requirements

* C compiler and standard build tools (make, sh, ...).

* [cmake](https://cmake.org/)

## Building

Standard cmake build (`make test` runs the test suite):

    $ cd bin

    $ cmake ..

    $ make

    $ make test

    # make install

## Using

Start the interpreter in interactive mode:

    $ tcbasic

Execute a program from a file in batch mode:

    $ tcbasic sample.bas

## Example Program

    10 REM Square Root Calculator using Newton's Method

    

    100 LET X = 1337

    400 GOSUB 1000

    500 PRINT "The square root of ",X," is approximately ",Y

    600 END

    

    1000 REM Calculate the square root of a given Number

    1001 REM Expects input to be in X. Output will be in Y.

    1002 REM Uses Z as a temporary variable.

    1050 LET Y = 0.5 * X

    1100 LET Z = Y

    1200 LET Y = Y-(((Y^2)-X)/(2*Y))

    1300 IF Z <> Y THEN GOTO 1100

    1400 RETURN
