Dollar sign

$

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

Pascal

As a PXSC extension, the symbol $, pronounced “dollar sign”, is used 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}.
