.SH DESCRIPTION
.I M11
assembles the concatenation of the specified files (\fIfile1\fP, etc.)
and terminates when an ``.end'' statement is encountered.  The
resulting object file is usually named  \fIfilen.obj\fP (see
below).  If a file argument, \fIfilei\fP does
not contain a ``.'' in its name, the file \fIfilei.m11\fP
will be sought before \fIfilei\fP itself.
.sp 2
Options, if desired, may appear anywhere in the command,
and are chosen from the following list.
All options are interpreted before any files are read.
.sp
.TP
.B \-\^ls
Produce an assembly listing and place in
.IR filen .lst
.TP
.B \-\^lt
Produce an assembly listing on the standard output.
.TP
.B \-\^fl
If coupled with the
.I \-ls
or
.I \-lt
directives, makes the listing have a shortened format.
It is shorthand for
.IR \-nl:seq:loc:bin:bex:me:meb:ttm:toc:sym .
.TP
.B \-\^uc
Simulate an initial
.I ".dsabl lc"
directive.
Force all characters in macro definitions to be upper case.
This flag makes lower-case handling in 
.I m11
compatable with the DEC Macro-11 assemblers.
.TP
.B \-\^um
Force all characters in macro definitions to be upper case.
This flag makes lower-case handling in
this release of
.I m11
compatable with previous versions of
.IR m11 .
.TP
.B \-\^de
Make all option choices needed to make assembly mimic DEC
Macro-11.  Implies
.I "(inter alia)"
the 
.I \-uc
flag.
This includes the Johns Hopkins
.I asm
assembler.
.TP
.B \-\^ha
Make all option choices needed to make assembly mimic earlier
(Harvard) releases of m11.
This implies the
.I \-um
flag.
Default .psect and .csect attributes are set up in the funny Harvard way.
.TP
.B \-\^mx
Produce a listing of the source program as it appears
.I after
macro expansion.
Macro calls, conditional directives and so on appear in the listing as comments.
Listing appears on standard output. 
No machine code is generated or listed.
This option is meant to correspond to the \-E or \-P
options of the C compiler
.I cc(1).
.TP
.B \-\^my
Like
.IR \-mx ,
except that macro calls and conditional directives do
not show up in the listing.
.TP
.B \-\^10
Generate an error whenever op codes not in the 
PDP-11 ``standard instruction set''
are encountered.
Programmers writing for a PDP 11/10 can catch instructions illegal for
that machine by using this argument.
.TP
.B \-\^dp:args
The default attributes for a
.I .psect
or unnamed
.I .csect
are redefined, using  the colon-separated list
.I args
of valid .psect attributes.
.TP
.B \-\^da:args
The default attributes for an
.I .asect
are redefined.
.TP
.B \-\^dp:c
The default attributes for a named
.I .csect
are redefined.
.TP
.B \-\^li:arglist
Simulate an initial
.I ".list arglist"
directive.
All
.I .list
and
.I .nlist
directives in the program text which attempt to change the settings established
with the
.I \-li
flag will be ignored.
.TP
.B \-\^nl:arglist
Like
.I \-li:arglist,
but for the
.I .nlist
directive.
.TP
.B \-\^en:arglist
Similarly, for the
.I .enabl
directive.
.TP
.B \-\^ds:arglist
Similarly, but for the
.I .dsabl
directive.
.TP
.B \-\^cr:arglist
Produces a cross-reference listing.
If the
.I \-ls
option is also included, the cross-reference listing will follow the
assembly listing in
.IR filen .lst.
References which are tagged with the symbol # are definitions.
References tagged with * are destuctive references: the value of the
symbol or variable in question is changed.
.I Arglist
consists of colon-separated keywords from the following set.
The keywords may be prefix abbreviated:
.RS
.TP
sym
All user-defined symbols are indexed.
.TP
mac
All macro names are indexed. 
.TP
per
All uses of permanent symbols \- op codes, directives, etc \-
are indexed.
.TP
pse
All psect names are indexed.
For compatability with the RT-11 
.I CREF
program, the argument
.I cse
is synonymous with
.I pse.
.TP
err
All errors are indexed.
.TP
reg
All register uses are indexed.
.PP
If no
.I arglist
is specified the default
.I "sym:mac:err"
is used.
In the listing page and line numbers for uses of symbols
are followed by a # sign if the symbol is defined and by a * sign
if the symbol is modified.
.RE
.TP
.B \-\^lp
Same as \-ls, but also spools
.IR filen .lst
for printing upon completion.
.TP
.B \-\^no
No object file is produced.  This is useful for
syntax checking or list producing.
.TP
.B \-\^xs:n
Allots nK words of extra space for
symbol table and macro storage.
NOTE:
This option is currently inoperative:
.I m11
automatically allots core for its tables as needed.
.TP
.B \-\^xx
Debug flag: generate all kinds of wierd hack flack.
.TP
.B \-\^ns
No symbol table is included in the object file
(thus ddt knows of no symbols from this assembly).
.TP
.B \-\^sx
Make the symbol table contain ``local symbols'' as well as
ordinary symbols.
.TP
.B \-\^u
Treat form feed characters as spaces.  This will make
.IR m11 's
idea of line numbers coincide with the UNIX text editors.
Macro-11 statements containing imbedded form feed characters will
be parsed differently when the 
.I \-u
flag is in effect.
.TP
.B \-\^na:file	
Override the convention of using last name
as file name.
Instead, use names
.I file.obj
and
.I file.lst
for object and listing files.
.SH NOTES
This implementation of Macro-11 is a distant hand-me down from
an old DEC Macro-11 modified at Harvard University in the early
1970's.
It is grubby with smudges by Brent Byer, F. J. Howard,
Bob Bowering, and Jim Reeds.
It does not implement keyword arguments such as are described in
section 7.3.6 of the DEC manual.
The .enabl abs option does not work.
Listing control is by default .list ttm.
Unlike earlier editions of m11 at UCB and at Harvard, it does
treat immediate constants of floating point operations correctly:
see the last paragraph of section 6.4.2 on the middle of page 6-27 of
the DEC manual.
M11 has several directives not described in the DEC manual.
See the
.I "New UCB M11 Manual."
The default attributes for
.I .psects
are different from those described in the DEC manual, but may be changed
by the
.I \-dp
flag.
The 
.I ".enabl glb"
feature is implemented:
undefined symbols are taken as undefined global externals.
