note from Don Knuth

[Maggie McLoughlin]

dvitype --help says that -output-level is a verbosity level from 0 to 4;
however, 0 doesn't work. [I simply want to see the fonts used,
as in the dvitype I wrote...]

Also, level 1 fails; it thinks characters of cmr10 are invalid, etc.

-- Don Knuth

[Sebastian Rahtz]

looks like a pretty unarguable error in dvitype.ch:

end else if argument_is ('output-level') then begin
out_mode := atou (optarg);
if (out_mode = 0) or (out_mode > 4) then begin
write_ln (stderr, 'Value for --output-level must be >= 1 and <= 4.');
uexit (1);
end;

in clear conflict with:

@ @<Determine the desired |out_mode|@>=
1: write(term_out,'Output level (default=4, ? for help): ');
out_mode:=the_works; input_ln;
if buffer[0]<>" " then
if (buffer[0]>="0")and(buffer[0]<="4") then out_mode:=buffer[0]-"0"
else begin write(term_out,'Type 4 for complete listing,');
write(term_out,' 0 for errors and fonts only,');
write_ln(term_out,' 1 or 2 or 3 for something in between.');
goto 1;
end

hard to see any reason not to change it straightaway in the web2c
stuff

Olaf, Thanks for looking into this.

The problem I reported with dvitype level 1 was actually my own fault; I had
a spurious "cmr10.tfm" in the directory from which I was running dvitype.
The same behavior occurs also with levels 2, 3, and 4 when that file
is present.

The file date of cmr10.tfm was June 1999, when I first got my machine.
For some reason that tfm file has never confused dvips, which I've used
a thousand times from the same directory since June. Thus dvips and dvitype
have different conventions for accessing tfm files. Perhaps tex-k should
look into this?

I append a shell listing which explains all, in case the above is unclear.

Cordially, Don Knuth

Correct; dvips uses the tfm widths from the PK file since it (generally)
has to read the PK file anyway.

I'm looking for a resource to explain Don Knuth's
book Fundamental Algorithms. Do you know of any?
