13.1.2 Procedure statements

Procedure statements are calls to subroutines. There are different possibilities for procedure calls:

• A normal procedure call.

• An object method call (fully qualified or not).

• Or even a call to a procedural type variable.

All types are present in the following diagram:

The Free Pascal compiler will look for a procedure with the same name as given in the procedure statement, and with a declared parameter list that matches the actual parameter list. The following are valid procedure statements:

Usage;
WriteLn('Pascal is an easy language !');
Doit();

Remark When looking for a function that matches the parameter list of the call, the parameter types should be assignment-compatible for value and const parameters, and should match exactly for parameters that are passed by reference.
