NAME
     as - assembler

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

DESCRIPTION
     _A_s assembles the concatenation of the named files.  The
     options are:

     -    Treat all undefined symbols in the assembly as external
          globals.

     -V   Produce an object suitable for loading into an
          automatic text overlaid program.

     -o   Use _o_b_j_f_i_l for the name of the resultant object.  If
          this is omitted, _a._o_u_t is used.  If no errors occurred
          during the assembly and if there were no unresolved
          external references, it is made executable.

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

DIAGNOSTICS
     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

BUGS
     Syntax errors can cause incorrect line numbers in following
     diagnostics.
