Languages Focus: Case Sensitivity

Case sensitiviy in this case is referring to commands and variable names. For example, are "printf" and "PrintF" equivalent? Are fullname and FullName equivalent? When you create commands, operations, methods, or variables should you worry about case?

Delphi Prism Case Sensitivity

Prism is generally not case sensitive. Commands and variable names are not case sensitive.

Note: Prism (and Delphi for .Net) do not automatically match your typed case with the defined case as C# and VB.Net do within the Visual Studio Shell.

Syntax Example:

The following demonstrates command and variable case insensitiviy.

var
 FullName: String;
begin
 fullname := 'Mike Prestwood';
 MessageBox.Show(fullNAME);
 MESSAGEBOX.SHOW(FULLNAME);
 messAGEbox.sHow(fullname);
end;
