@echo

We'll start with the @echo directive since it is very useful for debugging and demonstrating future directives.

The @echo directive takes a single string or expression argument and prints it to stderr.

Examples

@echo "Hello World"

Note that expressions are always printed in base 10.

@echo $1234 + $5678 ; Prints "26796" 

Methods of constructing strings out of expressions and printing in other bases will be covered later.
