The showstop function displays a report of all functions containing breakpoints, all watchpoints, and all error watchpoints currently set.

f := proc(x) local y; if x < 2 then y := x; print(y^2) end if; print(-x); x^3 end proc:

$\mathrm{stopat}\left(f\right)$

$\left[f\right]$

$\mathrm{stopat}\left(f\&comma;2\right)$

$\left[f\right]$

$\mathrm{stopat}\left(\mathrm{int}\right)$

$\left[f\&comma;\mathrm{int}\right]$

$\mathrm{stopwhen}\left(f\&comma;y\right)$

$\left[\left[f\&comma;y\right]\right]$

$\mathrm{stopwhen}\left(\mathrm{Digits}\right)$

$\left[\mathrm{Digits}\&comma;\left[f\&comma;y\right]\right]$

$\mathrm{stopwhenif}\left(\mathrm{answer}\&comma;42\right)$

$\left[\mathrm{Digits}\&comma;\mathrm{answer}\&comma;\left[f\&comma;y\right]\right]$

$\mathrm{stoperror}\left(\mathrm{`division\; by\; zero`}\right)$

$\left[''division\; by\; zero''\right]$

$\mathrm{showstop}\left(\right)$
