Scope/Function names and labels: Difference between revisions

=={{header|XPL0}}==

Function names follow the scoping rules of Algol. A function is a

procedure that returns a value.

A procedure name is visible from the point it's declared to the end of

the procedure in which its declaration appears. A complete program is a

procedure, informally called "main."

A procedure name is also visible in any sub-procedures that might be

nested in the procedure. If the same name is declared at different levels

in nested procedures, the most local declaration is used. Procedures can be nested up to eight levels deep.

There are no labels in XPL0 (except for inline assembly code).
