I was reading through the 2012 standard and found the following in Annex C, which talks about compatibility with older forths and notes changes that might need to be made:
Decimal, hexadecimal, binary number literals can now be written irrespective of BASE by using the prefix #, $, %. Also, character literals can be written as 'c'. Standard programs are unaffected. Systems have to be changed to recognize these forms.
The means that 'a' should be recognized as the letter "a" and $ABCD is always a hex value and #1234 is always a decimal value and %10110 is always a binary value, regardless of BASE.

There's also a link to 3.4.1.3 Text interpreter input number conversion that says essentially the same thing.
