# BASIC
BASIC interpreter
## Installation
1. You need to have at least version`v14.0.0` of [node.js](https://nodejs.org/en/) installed.
2. Install the `node-basic-lang` library globally:
```bash
npm install -g node-basic-lang
```
## Executing files
1. Create a BASIC program using the [supported commands](#supported-commands) below. Make sure that the file ends in `.bas`.
2. Run the BASIC program that you created
```bash
basic .bas
```
Example:
```bash
basic game.bas
```
## Using the REPL
You can use the REPL just by running the following command in the terminal:
```bash
basic
```
Make sure that you enter a unique line number for each command, just like you would a normal file. See [supported commands](#supported-commands) below for a list of commands you can use.
## Supported commands
`ABS` - Prints out the absolute value of a number.
`CLS` - Clears the console.
`INT` - Prints out an integer by rounding any decimal number down.
`PRINT` - Prints lines to the console.
`REM` - Comments for the user. The interpreter ignores these lines.
`END` - Exits the program.
## Sample file
```bas
10 CLS
20 REM "BASIC HELLO WORLD PROGRAM"
30 PRINT "HELLO WORLD"
40 PRINT "HELLO WORLD 2X"
50 PRINT "HELLO WORLD 3X"
60 ABS "-3.14"
70 INT "1.6180"
80 END
```
