End of Statement (Cross Ref > Statements)

By Mike Prestwood

ObjectPAL versus C++/CLI: A side by side comparison between ObjectPAL and C++/CLI.

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.

End of Statement

[Other Languages]

Languages Focus

In coding languages, common End of statement specifiers include a semicolon and return (others exist too). Also of concern when studying a language is can you put two statements on a single code line and can you break a single statement into two or more code lines.

ObjectPAL: whitespace

ObjectPAL is a bit unique in that it doesn't use a semicolon nor a return to mark the end of a line, it uses whitespace which can be a return, space, or tab. This is a bit unusual but does allow for some nice formatting of code.

Syntax Example: 1 certification question.

msgInfo("", "Hello1")
msgInfo("", "Hello2")
msgInfo("", "Hello3")
 
;The following single line of code also works.
msgInfo("", "Hello4")   msgInfo("", "Hello5")
 
;Two or more works too:
msgInfo
  ("", "Hello6")

C++/CLI: ;

Same as standard C++. C++ uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code if you wish as well as split a single statement into two or more code lines.

Syntax Example:

//.Net WinForms example.

//Add, using namespace System::Windows::Forms;

MessageBox::Show("Hello1");

MessageBox::Show("Hello2");

MessageBox::Show("Hello3");

MessageBox::Show("Hello4"); MessageBox::Show("Hello5");

MessageBox::

  Show

    ("Hello6");
