Another option which does not require debug to be on is to embed the verb in a
try. catch. end. control block
tracer=: 4 : 0
try. x + y
catch. 2 3 $ 'x arg';'Error Type';'y arg'; x;(, 13!:12 '');y end.
)
4 tracer 5
9
4 tracer 'a'
┌─────┬──────────────────────────────────┬─────┐
│x arg│Error Type │y arg│

'd' tracer 3
