Everybody loves the
\show tex primitive.
Sadly it so happens that whenever I
\show something the execution/compilation which I call using
pdftex -halt-on-error also stops, which was quite supprising to me having not perceived
\show primitive to be an error. Can somebody please tell me to stop
\show behaving like an error? Why was it behaving like an error in the first place?
the output after a show was used like this
is the following
>\a=macro: ->A. l.2 \show \a ! ==> Fatal error occurred, no output PDF file produced!
Besides my testing, also this answer here tells about
\shows behavioral problems it states
TeX will prompt the user for interaction in the event of an error ('error' includes
\showor similar) (The user may of course alter the run mode within TeX using the related primitives.)
This seems to motivate this question further, as if I understand right there is a way to alter the run mode within TeX. I think that would be the way to stop
\show being an error, but how?
