Subject: Re: How das Ruby work

Hi,

It's an interpreter, so what happens is... you run your code with the  
"ruby" command, which does the following:

1. The interpreter goes through your code, instruction by instruction.
2. As it goes through your code, it converts each instruction into  
machine language.
3. Instruction by instruction, as it is converted to machine language,  
it is executed.

This is akin to a human language interpreter (rather than a human  
language translator) - ie people whose job it is to convert  
communication between two people speaking different languages.

A human language interpreter will translate each phrase as it is  
spoken, whereas a human language translator isn't under the "hammer"  
so much so to speak, so the product that they produce will be akin to  
a piece of software that is compiled - once finished, it is much  
faster to run the code, and likewise once translated, it is much  
faster to communicate the required communication.

Hope this helps.

Julian.
