Delphi Prism Topic:
Code Snippet of the Month

Prism supports type inference where you just use a variable and the compiler will then choose the lowest type possible (such as an Integer before a LongInt). With Prism, you frequently do not have to use commands to convert from one type to another. Variable names are not case sensitive. The Prism language offers both old-style declaring variables before the begin as well as inline variable declaration. Prism does support variable initialization too. Prism offers many variable types. Some common variable types include Integer, LongInt, Single, Double, Boolean, and String.

var

FName: String; //This is old-style.
begin
FName := "Mike Prestwood";
MessageBox.Show(FName);

Var Age: LongInt; //Local variables.
Age:=36;
MessageBox.Show(Fname + " is " + Age + " years old");

//Assign values too...
Var Wife: String:="Lisa"; Var WifeAge: Integer:=32;
messagebox.Show(wife + " is " + Wifeage + ".");
end;
