[NTG-context] Showing value of a MP variable

Hello, is it possible (namely for debugging) values of MP variables (be it on the console or in the log)? I thought there is MP command "show" (mentioned in mpman.pdf) for this; but: ---- \starttext A \startMPcode newpair pt; pt := (10,20); show pt; % <-------------------------- How to show the value? drawdot pt; \stopMPcode \stoptext ---- doesn't show value of 'pt' variable.
