Arguments
---------

   "Arguments" are symbols, numbers or subexpressions.  In other
contexts arguments are sometimes called "arithmetic operands".  In this
manual, to avoid confusing them with the "instruction operands" of the
machine language, we use the term "argument" to refer to parts of
expressions only, reserving the word "operand" to refer only to machine
instruction operands.

   Symbols are evaluated to yield {SECTION NNN} where SECTION is one of
text, data, bss, absolute, or undefined.  NNN is a signed, 2's
complement 32 bit integer.

   Numbers are usually integers.

   A number can be a flonum or bignum.  In this case, you are warned
that only the low order 32 bits are used, and `as' pretends these 32
bits are an integer.  You may write integer-manipulating instructions
that act on exotic constants, compatible with other assemblers.

   Subexpressions are a left parenthesis `(' followed by an integer
expression, followed by a right parenthesis `)'; or a prefix operator
followed by an argument.
