       as - assembler

       as [ - ] [ -o objfile ] file ...

       As  assembles  the  concatenation of the named files.  If the optional first argument - is
       used, 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.
       It  is  executable  if  no errors occurred during the assembly, and if there were no unre-
       solved external references.

       /lib/as2       pass 2 of the assembler
       /tmp/atm[1-3]? temporary
       a.out	      object

       ld(1), nm(1), adb(1), a.out(5)
       UNIX Assembler Manual by D. M. Ritchie

       When an input file cannot be read, its name followed by	a  question  mark  is  typed  and
       assembly  ceases.   When syntactic or semantic errors occur, a single-character diagnostic
       is typed out together with the line number and the file name in which it occurred.  Errors
       in pass 1 cause cancellation of pass 2.	The possible errors are:

       )  Parentheses error
       ]  Parentheses error
       <  String not terminated properly
       *  Indirection used illegally
       .  Illegal assignment to `.'
       a  Error in address
       b  Branch instruction is odd or too remote
       e  Error in expression
       f  Error in local (`f' or `b') type symbol
       g  Garbage (unknown) character
       i  End of file inside an if
       m  Multiply defined symbol as label
       o  Word quantity assembled at odd address
       p  `.' different in pass 1 and 2
       r  Relocation error
       u  Undefined symbol
       x  Syntax error

       Syntax errors can cause incorrect line numbers in following diagnostics.
