In the MWE below I would expect the "show" command to print the value of
p in the console output (I use Texworks), however this does not seem to
be happening. I haven't used "show" in MetaFun for a while, am I
implementing it correctly?

%%%%%%%% MWE %%%%%%%%%
\setuppapersize[A4, portrait]
\starttext
\startMPpage
StartPage;
width := PaperWidth ; height := PaperHeight ; unit := cm ;
numeric p;
p := 0;
for q = 0 step 1 until 10:
show p;
p := p + 1;
fill fullcircle xyscaled(3cm,4cm) shifted ((p +2)*cm, (p + 2)*cm)
withcolor red ;
endfor;
StopPage;
\stopMPpage
\stoptext

\enabletrackers[metapost.tracingall]
but best use:
message(p);

Thanks Hans!
I had forgotten about \enabletrackers[metapost.tracingall].
