  Is that the Unix assembler convention? 
Yup. From "Unix Assembler Reference Manual" (by DMR; no date, but the one
I'm
looking at came with V6): "An octal constant consists of a sequence of digits
... A decimal constant consists of a sequence of digits terminated by a decimal
point '.'."

...
  It certainly isn't the one used by the GNU
assemblers, which are modeled
 after the old Unix syntax. 
Except when they gratuitously change things.
