Turbo Pascal - Sample Code

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.

Famous quotes containing the words sample and/or code:

    “All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
    —Peter Conrad (b. 1948)

    “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)
