begin

     The Begin keyword is fundamental to PASCAL - it starts statement blocks. The Begin-end pair fence in a set of statements. You may place such a block anywhere in your code. It is particularly sensible in if and for statements, even if only one statement is required. It means that adding an additional statement in the future is easy.

var
  myChars : array[1..2] of char;
  myBytes : array[1..2] of Byte;
  i : Integer;

// The begin statement always starts the code part of a subroutine
Begin
  // Use a for block to assign to both arrays
  for i := 1 to 2 do Begin
    myChars[i] := Chr(i+64);
    myBytes[i] := i+64;
  end;

  // Use a for block to observe the contents
  for i := 1 to 2 do Begin
    Writeln('myChars[',i,'] = ',myChars[i]);
    Writeln('myBytes[',i,'] = ',myBytes[i]);
  end;
end.

Output

myChars[1] = A
myBytes[1] = 65
myChars[2] = B
myBytes[2] = 66
