Procedure Types

Procedure types contain the address of a procedure or function. Procedure types are followed by blocks of data and code and are defined as follows:

  procedure identifier [(Parameterlist)]}

  function identifier [(ParameterList)] : ReturnType}

ReturnType is the type of value returned by the function. ParameterList is defined as:

  Parameter [;Parameter]}

where Parameter is:

  [var] identifier [,identifier] : Typename}

var specifies a variable parameter. The var parameters are passed by reference as opposed to being passed by value.

The following are examples of procedure types:

procedure PrintAt(X, Y: Integer; S: String);
function Max(Value1, Value2: Integer): Integer;
procedure GetDir(Driver: Byte; var S: String);
