$

In ASCII, the character code decimal 36 (or hexadecimal 24) is defined to be $ (dollar sign).

Pascal

The symbol $, pronounced “dollar sign”, is used in Pascal to indicate a hexadecimal base.

program dollarSignDemo(input, output, stderr);

var
	i: longint;

begin
	// '$' as well as '0x' are recognized by readLn
	// as hexadecimal base prefixes
	readStr('$24', i);
	writeLn(i);    // will print  36
	writeLn(-$24); // will print -36
end.

An optional sign is written in front the base indicator.

other appearances

For FPC and Delphi compilers, the dollar sign appears in compiler directives of the form {$directive}.
