There were some errors in your input, and groff 1.22.4 mm was not very helpful about identifying them, nor did its groff_mm(7) man page make terribly clear what you should be doing. When I try your input with groff 1.23.0, released last month, I get the following error. $ ~/groff-stable/bin/groff -ww -b -mm -Tutf8 ATTIC/eder-letter.mm |cat -s m.tmac:.../groff-stable/share/groff/1.23.0/tmac/mm/5.MT:48: error: title not defined; call TL and AU before MT A problem is that, as noticed in the original thread from 2½ years ago, is that you should have been using either: 1. The `AU` and `TL` macros _both_ with `MT`, or 2. The `WA` and `WE` macros with `LT`. Another problem was that you gave 2 arguments to the `FC` macro when it accepts only one. The man page has some new language about these matters. Document styles groff mm offers three different frameworks for document organization. COVER/COVEND is a flexible means of preparing any document requiring a cover page. LT/LO aids preparation of typical Anglophone correspondence (business letters, for example). The MT memorandum type mechanism implements a group of formal styles historically used by AT Bell Laboratories. Your document can select at most one of these approaches; when used, each disables the others. [...] Macros [...] AU [name [initials [loc [dept [ext [room [arg1 [arg2 [arg3] Specify author. AU terminates a document title started with TL, and can be called without arguments for that purpose. Author information is used by cover sheets, MT memoranda, and SG. Further arguments comprise initials, location, department, telephone extension, room number or name, and up to three additional items. Repeat AU to identify multiple authors. Use WA/WE instead to identify the author for documents employing LT. [...] FC [closing‐text] Output the string Letfc, or the specified closing‐text, as the formal closing of a letter. [...] LT [style] Format a letter in the designated style, defaulting to BL (see below). A letter begins with the writer’s address (WA/WE), followed by the date (ND), the inside address (IA/IE), the body of the letter (P and other general‐ purpose mm macros), the formal closing (FC), the signature (SG), and notations (NS/NE). Any of these may be omitted. Letter options specified with LO add further annotations, which are extensible; see section “Internals” below. style Description BL Blocked: the writer’s address, date, formal closing, and signature are indented to the center of the line. Everything else is left‐aligned. SB Semi‐blocked: as BL, but the first line of each paragraph is indented by 5m. FB Fully blocked: everything begins at the left margin. SP Simplified: as FB, but a formal closing is omitted, and the signature is set in full capitals. I used DWB 3.3 mm as my basis for comparison. It requires as well the `IA`/`IE` macros for an inside address to be called for `LT` letters, but they need not have any content. groff mm doesn't demand them. DWB 3.3 mm also does not put anything in boldface or italics in `LT` letters. The examples in its manual also do not exhibit such style changes. groff mm (in 1.23.0) uses only one blank line of vertical spacing at most between segments of the letter. I judged this to be the best approach since there is no standard defining how large these gaps should be--one vee seemed a reasonable minimum that people could alter within a letter with `SP` calls, as you did, and anything not covered by that technique, we can add registers for, probably in the `Letxxx` name space. I had problems with Heirloom Doctools mm. It appears to believe that no authors are defined. It also throws some garbage on the output. But it also doesn't do any font style changes as you seemed to be expecting. This at least is consistent with DWB 3.3 (Heirloom's predecessor). ~/heirloom$

Re: problem with mm macros

Just a brief follow-up to this: the test in the patch is
for a string expansion that returns nothing, in this case
usually because the string is not defined, and then groff
gives a warning.
There are two obvious ways to fix this: either an explicit
empty string that signifies the end of the author's titles,
or storing the number of titles in a register. Both require
one extra register per author, but I think the latter is better,
since it easily allows using .ne to request enough space to
output an author's signature block without page breaks.
With that in mind, here's a better patch (relative to the
original m.tmac). No provision is made for single titles
that are so long that they take more than one line to print.

Re: problem with mm macros
Thanks, I will try it out. And if the LT macros are still broken, I'll put in a report. I think they will be, as the LT macros are (I believe) a non-standard addition to GNU mm, separate from the MT macros. Robert. On Mon, Mar 15, 2021 at 4:02 PM Dave Kemper wrote: > Thanks, Tadziu!

Thank you for fixing this, It works.
The only difference to either heirloom or neateqn output is that both
name and title are not in bold.
Wether this is impostant or not os a dofferent question.

Re: problem with mm macros
Thanks, Tadziu! I've attached your patch to http://savannah.gnu.org/bugs/?57034. Andreas and Robert, are the other issues you noted in this thread manifestations of the same problem, or separate problems? I'm not at all an mm user so don't know the expected behavior, but from the descriptions, it sounds like at least the .LT problem Robert reported is something different. Would you two mind opening new bugs in our bug tracker (http://savannah.gnu.org/bugs/?group=groff=additem) to document these problems if they're different from 57034? You can submit bug reports here without creating an account.

This can be fixed quickly by adding, below the line that
prints the author's name,
\\*[cov*au!\\n[let*i]!1]
the following lines:
.nr let*j 0 1
.while !'\\*[cov*at!\\n[let*i]!\\n+[let*j]]'' \{\
\\*[cov*at!\\n[let*i]!\\n[let*j]]
.\}
Since the number of titles for each author is not stored anywhere,
this assumes that an empty value signals the end of the author's
titles, i.e., there can be no empty author's titles (but \& works).
I noticed that the loc-dept-initials/initials line is also different.
Does anyone still use this? Is it important that this is
historically accurate?

Re: problem with mm macros
Actually, I now see that documents headed with .LT don't use .AU etc., but .WA. And for the most part it works. But there is still a bug, with one of the four types of letters. Try this: .LT SP .WA "John Doe" Nowhere, USA. .WE .IA "Jane Smith" Somewhere, UK. .IE .LO SJ "Letter of Introduction" .LO SA "Dear Ms Smith" .P This is the text of the letter. .FC "Yours sincerely" .SG You'll find that: The subject line shows only the first word; the formal closing is omitted completely; and the writer's name at the bottom is followed by a trailing comma. If you change the first line to .LT BL or one of the other types, everything is printed correctly. Robert.
