bs Statements

A computer program is a list of "instructions" to be "executed" by a computer.

In a programming language these programming instructions are called statements.

A BeasScript program is a list of programing statements.

 

BeasScript statements are composed of

Values, Operators, Expression, Keywords and comments.

 

This statement displays a message box with "Hello World".

 

messagebox="Hello World"

 

The statements are executed, on by one, left to right and top to bottom, in the same order as they are written.

 

Line Feed

LineFeed separate BeasScript statements

Add a semicolon at the end of each executable statement:

 
// assign the value 5 to a
setvar=a=5      

// assign the value 10 to b
setvar=b=10     

// display value from a, in this case "5"
messagebox=<a>   

 

BeasScript White space

Beas Script does not  ignore multiple spaces. Spaces and tabs are ignored only on the right and the left side.

 

Correct

setvar=a=5
       setvar=a=6

 

WRONG:

setvar =a=5 
setvar=a   =5
setvar=a=   5

 

BeasScript Keywords

BeasScript has many keywords. But BeasScript does not include a syntax check. If you use the wrong keywords, the system will ignore it and continue with the next line.

Below you can find a small overview of keywords you will learn about in this tutorial:
