End of Statement (Cross Ref > Language Basics)

End of Statement

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.

Access VBA: Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:

MsgBox "Hello1"
MsgBox "Hello2"
MsgBox "Hello3"

'The following commented code on a single line does not work...
'MsgBox "Hello4"  MsgBox "Hello5"
 
'Two or more lines works too with a space+underscore:
MsgBox _
 "Hello6";

ASP Classic: Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:

Response.Write("Hello1")
Response.Write("Hello2")
Response.Write("Hello3")
 
'The following commented code on a single line does not work...
' Response.Write("Hello4")  Response.Write("Hello5")
 
'Two or more lines works too with a space+underscore:
Response.Write _
  ("Hello6")

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: 1 certification question.

Console.WriteLine("Hello1");
Console.WriteLine("Hello2");  
Console.WriteLine("Hello3");
 
//Same line works too:
Console.WriteLine("Hello4");  Console.WriteLine("Hello5");

//Two or more lines works too: 
Console.

  WriteLine
    ("Hello6");

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:

printf("Hello1");

printf("Hello2");

printf("Hello3"); printf("Hello4");

printf

   ("Hello5");

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");

Corel Paradox: 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")

Delphi: ;

Object Pascal uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code and put a single statement on two or more code lines if you wish.

Syntax Example: 1 certification question.

WriteLn('Hello1');
WriteLn('Hello2');
WriteLn('Hello3');
 
//Same line works too:
WriteLn('Hello4');  WriteLn('Hello5');
 
//Two or more lines works too:
WriteLn
  ('Hello6');

Delphi Prism: ;

Object Pascal uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code and put a single statement on two or more code lines if you wish.

Syntax Example: 1 certification question.

MessageBox.Show("Hello1");

MessageBox.Show("Hello2");

MessageBox.Show("Hello3");
 
//Same line works too:

MessageBox.Show("Hello4");  MessageBox.Show("Hello5");
 
//Two or more lines works too: 
MessageBox.Show
  ("Hello6");

Java: ;

Syntax Example:

System.out.println("Hello");

JavaScript: ; is optional

In JavaScript, using a semicolon at the end of statements is optional. You might think a semicolon then is just another comment specifier but it is not. The semicolon is an optional end of statement specifier. To put two statements on a single code line, you must use a semicolon. However, the semicolon is optional, but probably confusing, when you break a single statement into multiple code lines.

Syntax Example:

document.write("Hello1");
document.write("Hello2");
 
//Semicolons are optional:
document.write("Hello3")
document.write("Hello4")
 
//This works too but only if you use a semicolon:
document.write("Hello5");  document.write("Hello6");
 
//Two lines also works:
document.write
  ("Hello7")

JavaScript End of Statement (; is optional)

Perl: ;

Syntax Example:

print "Hello";

PHP: ;

Syntax Example:

echo "Hello";

VB Classic: Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:

MsgBox "Hello1"
MsgBox "Hello2"
MsgBox "Hello3"
 
'The following commented code 
'on a single line does not work...
'MsgBox "Hello4"  MsgBox "Hello5"
 
'Two or more lines works too with a space+underscore:
MsgBox _
 "Hello6";

VB.Net: Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example: 2 certification questions.

Console.WriteLine("Hello1")
Console.WriteLine("Hello2")
Console.WriteLine("Hello3")
 
'The following commented code 
'on a single line does not work...
'Console.WriteLine("Hello4")  Console.WriteLine("Hello5")
 
'Two or more lines works too with a space+underscore:
Console.WriteLine _
 "Hello6";
