pdp-11 assembly standards

OK, what was the standard (if there was one) number-base syntax for PDP-11 assembler?

Despite all the PDP-11 assembly info on web sites, this seems to be a buried bit of info.
One assembler doc uses a prefix of "&o", another specifies octal as default and prefix of zero for decimal (opposite of the common C-derived standard . . great).

Is this for example standard?:

		BIT #&o200, @#&o177564		; test 2^7 bit at address octal 177564

(I'm just trying to make some written commentary consistent with common policy.)
