If Statement (Delphi and Delphi Prism Cross Reference Guide)

By Mike Prestwood

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

 
Statements
 

Common statements such as if statements, loops, etc.

If Statement

[Other Languages] 
Delphi:   If..Else If..Else

Notice in the more complete example that the semicolon for the begin..end block after end is not included. That tells the compiler something else is coming (the statement is not finished). Also note the semicolon is missing right before the final "else" statement.

Note: The following example uses floating point literals. In Delphi, to specify a fractional floating point literal between 1 and -1, you preceed the decimal with a 0; otherwise, you will get a compiler error (i.e. .1 + .1 does not work).

Syntax Example:
if (0.1 + 0.1 + 0.1) = 0.3 then
  ShowMessage('Correct')
else
  ShowMessage('Not correct');
 
//Complete example:
if x = true then
begin
  ShowMessage('x is true');
end
Else If y = 'Mike' Then 
  ShowMessage('hello mike')
Else 
  ShowMessage('last option');
Delphi Prism:   if..else if..else

Notice in the more complete example that the semicolon for the begin..end block after end is not included. That tells the compiler something else is coming (the statement is not finished). Also note the semicolon is missing right before the final "else" statement.

Syntax Example:
//Complete example:
if x = true then begin
  ShowMessage('x is true');
end
Else If y = 'Mike' Then 
  ShowMessage('hello mike')
Else 
  ShowMessage('last option');
