Sample Code
- Pascal is not case sensitive.
- Historically, Pascal comments are enclosed
{ within pairs of braces }
, or(* left parenthesis/asterisk and asterisk/right parenthesis pairs *)
, and these can span any number of lines. Later versions of Borland Pascal also supported C++-style comments// preceded by two forward slashes
, which finish at the end of the line. - The syntax for the statement
case
is more flexible than standard Pascal. - Sets may only have up to 256 (28) members.
- Standard, fixed-length Pascal strings are supported, but there is also a more flexible
String
type.
This is the classic Hello world program in Turbo Pascal:
program HelloWorld; begin WriteLn('Hello World') end.This asks for a name and writes it back to the screen a hundred times:
program WriteName; var i : Integer; {variable to be used for looping} Name : String; {declares the variable Name as a string} begin Write('Please tell me your name: '); ReadLn(Name); {ReadLn returns the string entered by the user} for i := 1 to 100 do begin WriteLn('Hello ', Name) end end.Read more about this topic: Turbo Pascal
Famous quotes containing the words sample and/or code:
“As a rule they will refuse even to sample a foreign dish, they regard such things as garlic and olive oil with disgust, life is unliveable to them unless they have tea and puddings.”
—George Orwell (1903–1950)
“Wise Draco comes, deep in the midnight roll
Of black artillery; he comes, though late;
In code corroborating Calvin’s creed
And cynic tyrannies of honest kings;
He comes, nor parlies; and the Town, redeemed,
Gives thanks devout; nor, being thankful, heeds
The grimy slur on the Republic’s faith implied,
Which holds that Man is naturally good,
And—more—is Nature’s Roman, never to be
scourged.”
—Herman Melville (1819–1891)
