When this extension is enabled (the default), the Irie Pascal compiler will recognize binary and hexadecimal constants.
Binary constants begin with %, and are followed by one or more binary (0 or 1) digits.
The following are examples of valid binary constants
%0 %1 %01110101010101010111101
The following are not valid binary constants
%2 % %151 %g
Hexadecimal constants begin with $, and are followed by one or more hexadecimal (one of 0123456789ABCDEF) digits.
The following are examples of valid hexadecimal constants
$9 $A123 $ffff
The following is not a valid hexadecimal constant
$abgd
since g is not a hexadecimal digit.
