bed_gdg@SHSU.BITNET ("George D. Greenwade") (02/21/91)
As I have been going through back issues of TeXhax stripping headers and
looking for interesting style/macro file contributions to place on FILESERV,
I came across a contribution in Volume 89, Issue 67 (Friday, July 14, 1989)
from Dimitri Vulis <DLV@CUNYVMS1.BITNET> for a weekday macro. Everything
above the commented in line is the original macro (which works as a LaTeX
style file I would like to ultimately name WEEKDAY.STY). Below the
commented line I am again showing my ignorance in TeX. Dimitri's
contribution yields Sunday, Monday, ... , Saturday from a date (i.e.,
placing in the command "\weekday{1776}{7}{4}," yields "Sunday,").
What I would like to do is make this read "Sunday, July 4, 1776,". That is
done in my modification, "\weekdaydisplay{1776}{7}{4}" (or at least appears
to be!). The problem is that Dimitri's command
"\weekday{\year}{\month}{\day}," yields "Wednesday" (the correct day as I
write this), but my variant of this "\weekdaydisplay{\year}{\month}{\day},"
yields only "Wednesday, Feburary, ," and the list file says:
! Missing number, treated as zero.
<to be read again>
,
\weekdaydisplay ...\or November\or December\fi \space #3,
\space #1
l.8 ...nclude \weekdaydisplay{\year}{\month}{\day}
,
?
! Missing number, treated as zero.
<to be read again>
,
l.8 ...clude \weekdaydisplay{\year}{\month}{\day},
?
I'm probably missing something obvious, but what?
