Code Blocks (Delphi and Delphi Prism Cross Reference Guide)

By Mike Prestwood

Delphi versus Delphi Prism: A side by side comparison between Delphi and Delphi Prism.

 
Language Basics
 

Language basics is kind of a catch all for absolute beginner stuff. The items (common names) I chose for language basics is a bit random and include items like case sensitivity, commenting, declaring variables, etc.

Code Blocks

[Other Languages] 

Languages Focus

The rules for code blocks within a language dictate where you can declare variables, how you "bracket" code, etc.

Delphi:   begin..end

Object Pascal requires the semi-colon after the "declaration" part.

Syntax Example:
function DoSomething : integer;
var
  a, b : integer
begin
  a := 1;
  b := 2;
  
  result := a + b;
end;
Delphi Prism:   begin..end

Same as in Delphi for Win32 but Prism also supports inline variable declaration.

Syntax Example:
function DoSomething : integer;
var
 a, b : integer;
begin
 a := 1;
 b := 2;
 var c : integer; //Prism allows inline (local) variables.
 c := a + b;
  
 result := c;
end;
