The first application, we are always obliged to write in a new language is "Hello World!". So here it is:
"Hello, World!"
""
"I'm Atalan."
That was easy :-) Atalan prints any text in double quotes (string) to display on separate line.
If you write variable name enclosed in square brackets inside string, it's contents will be printed.
a,b:0..255
a = 10
b = 20
c = a + b
"Sum of [a] and [b] is [c]."
