@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.
