⎕TRACE Trace

The nomadic system function ⎕TRACE displays the values of the assignments made on the lines specified in the left argument when the function, operator or method named in the right argument is executed.

Used without a left argument, the current trace settings are returned.

A left argument of 0, or an empty vector, removes trace control. For further details, see the earlier chapter on Stop and Trace control.

To use ⎕TRACE on a method of a class, the right argument should be the fully-qualified method name (i.e. the class name, a period, and the method name).
