 Pascal was a popular choice for microcomputers in the 70's and 80's, even more popular than C initially (C was still quite an UNIX-only language)
 due to its simple design, which allowed fast simple single-pass compilers.
 
+In its "vanilla" form, Pascal is not any more complex than C, aside from having features that C doesn't have, such as range types
+and nested procedures.

 ## Compilers

 for different OSes and architectures, libre software.

+### Returning values from functions
+```pascal
+{ The "classical" way, assigning the return value to the function name }
+function Square(n: integer): integer;
+begin
+    Square := n * n; 
+end;
+
+{ Object Pascal and Delphi, assigning to special `Result` variable }
+{ Enable with `-S2` in FPC }
