Thank you Thomas!
I had already tried \p, but it is difficult to get it to work inside the
refer support code in the macro packages used. It seems that such code has
to be embedded in these strings overriding the ones that are in the macro
package you are using.
.ds ref*spec!A ", " "
.ds ref*spec!B """ " " "in \fI" "" "\fP"
.ds ref*spec!D """ " " "(" ")"
.ds ref*spec!E ", " " "ed. "
.ds ref*spec!G """ " " "(" ")"
.ds ref*spec!J ", " " "\fI" "" "\fP"
.ds ref*spec!N """ "(" "" ")"
.ds ref*spec!O ". " "
.ds ref*spec!P ", " " "p.\~"
.ds ref*spec!PP ", " " "pp.\~"
.ds ref*spec!T ", " " "\\*Q" "" "\\*U"
.ds ref*spec!T:0 ", " " "\fI" "" "\fP"
.ds ref*spec!T:2 ", " " "\fI" "" "\fP"
.ds ref*spec!V """ " " "\fB" "\fR"
.ds ref*spec!dflt ", " "
And I could find no way to execute a request inside a string.
.nh 0
for a single refer field, in my case for field O.
My temporary solution is to override the bibliographic item start and end
macros, which are specific for each macro package, but executed in the
general refer code. Here I turned off the hyphenation and adjustment, but I
do that for the entire reference, which isn't really what I want. Further,
this breaks if there is a page break inside a reference :(
.de ref*biblio-item-start
. IP "\\$1"
. hy 0
. na
..
.de ref*biblio-item-start-nolabel
. XP
. hy 0
. na
..
.de ref*biblio-item-end
. hy
..
Anyway, there is a lot to do for getting refer support that works with
digital references....
Yours,
Sigfrid
