                     35: .I As
                     36: assembles the named files, or the standard input if no file name is specified.
                     37: The available flags are:
                     38: .TP
                     39: .B \-a
                     40: Specifies the alignment of procedures and data blocks.
                     41: It is given as a power of two; thus an alignment of 3
                     42: causes alignment on an eight byte boundary.
                     43: The default is
                     44: .B \-a2.
                     45: .TP
                     46: .B \-d
                     47: Specifies the number of bytes to be assembled for offsets
                     48: which involve forward or external references, and which have sizes unspecified
                     49: in the assembly language.
                     50: The default is 
                     51: .B \-d4.
                     52: .TP
                     53: .B \-L
                     54: Save defined labels beginning with a `L', which are normally discarded
                     55: to save space in the resultant symbol table.
                     56: The compilers generate such temporary labels.
                     57: .TP
                     58: .B \-V
                     59: Use virtual memory for some intermediate storage,
                     60: rather than a temporary file.
                     61: .TP
                     62: .B \-W
                     63: Do not complain about errors.
                     64: .TP
                     65: .B \-J
                     66: Use long branches to resolve jumps when byte-displacement branches are
                     67: insufficient.  This must be used when a compiler-generated assembly contains
                     68: branches of more than 32k bytes.
                     69: .TP
                     70: .B \-R
                     71: Make initialized data segments read-only, by concatenating them to
                     72: the text segments.
                     73: This obviates the need to run editor scripts on assembly
                     74: code to make initialized data read-only and shared.
                     75: .TP
                     76: .B \-t
                     77: Specifies a directory to receive the temporary file, other than
                     78: the default /tmp.
                     79: .PP
                     80: All undefined symbols in the assembly
                     81: are treated as global.
                     82: .PP
                     83: The output of the assembly is left on the file
                     84: .I objfile;
                     85: if that is omitted,
                     86: .I a.out
                     87: is used.
