In reply to the following:

The as doc in info says:

	A binary integer is '0b' or '0B' followed by zero or more of
	the binary digits '01'.

	An octal integer is '0' followed by zero or more of the octal
	digits ('01234567').

	A decimal integer starts with a non-zero digit followed by zero
	or more digits ('0123456789').

	A hexadecimal integer is '0x' or '0X' followed by one or more
	hexadecimal digits chosen from '0123456789abcdefABCDEF'.

I checked this out -- fed an instance of each format to "as" and then
disassembled the a.out; it worked as expected.
