Raven Manual - Whitespace and Indentation

As of version 20060130, the engine does not care whether you use spaces (ASCII #20) or tabs (ASCII #9) to indent source code blocks. However, it is best to choose one or the other and be consistent. My preference is to use tabs for indentation and spaces for alignment. Eg:

define some_function 
<tab>"hello world\n".......print 
<tab>"and goodbye world\n".print 

The <tab> defines the indentation of the body of the function. The . (space) aligns the print statements. The following code is identical and preferable for some folks:

define some_function2 
...."hello world\n".......print 
...."and goodbye world\n".print
