SYNOPSIS

as [ −d124 ] [ −o objfile ] [ file ]

DESCRIPTION

As assembles the named file, or the standard input if no file is specified.  The optional argument −d may be used to specify the number of bytes to be assembled for offsets which involve forward or external references.  The default is four bytes, i.e., −d4 .  All undefined symbols in the assembly are treated as global. 

The output of the assembly is left on the file objfile; if that is omitted, a.out is used.
