# ScriptBasic for Java

This project needs volunteers who read the outdated documentation and update it in Markdown or ASCIIDOC.

If you consider contributing please fork the project and start writing documentation. I will happily credit.

ScriptBasic for Java is a BASIC interpreter that can be embedded into Java programs. With SB4J you can

script your application (or let the users to script) in good old BASIC. You can start in the JVM an

interpreter and execute for example:

```

PRINT "hello, I am BASIC"

PRINT "\nthe numbers from 1 to 10 are\n"

FOR I=1 to 10

  PRINT I,"\n"

NEXT I

```

SB4J has all the BASIC language features, assignments, loops, subroutines, global and local variables and

no `GOTO` statement. Seriously. 

To embed the interpreter into your application you need to use SB4J as a dependency

```

  

    com.scriptbasic

    jscriptbasic

    2.1.1

  

``` 

and then use the JSR223 defined scripting interface or use the ScriptBasic specific integration API.

The simplest way is to use the line

```

     ScriptBasic.engine().eval("PRINT \"hello world\"");

```

to get an execution engine and `eval()` the program source. There are other possibilities. You can

specify the file where the source code is, a `java.io.Reader` to read the source code and

there are even more advanced possibilities.

The BASIC language contains all the usual BASIC features, subroutines, local and global variables,

conditional statements, loops and so on. (No GOTO!) Your host program can directly call subroutines, read

and write global variables, provide methods implemented in Java to be called from BASIC code.

The interpreter can safely be integrated to applications as the BASIC programs cannot access

arbitrary objects and call Java methods at their will and there are other features that help

controlling the scripts in the application. The language is a "no freak out" language, so you

can put the programming possibility into the hands of users who would not ever touch Python, Groovy

or some other programming language but are happily craft their code in BASIC.
