OpenersNotesSection(Spacer1)Details

This message is generated when the value of the (RefLink[TraceBackward, paclet:ref/TraceBackward]) or (RefLink[TraceForward, paclet:ref/TraceForward]) option is not (RefLink[True, paclet:ref/True]), (RefLink[False, paclet:ref/False]), or (RefLink[All, paclet:ref/All]).

(RefLink[Off, paclet:ref/Off])[message] switches off the message; (RefLink[On, paclet:ref/On])[message] switches it on. For example: (RefLink[Off, paclet:ref/Off])[Trace::tracd].

An error occurs because a number is not a valid value for the (RefLink[TraceBackward, paclet:ref/TraceBackward]) option:

Trace[3+Cos[Pi]+Sin[Pi],2,TraceBackward->2]

This shows a valid value for the (RefLink[TraceBackward, paclet:ref/TraceBackward]) option in (RefLink[Trace, paclet:ref/Trace]):

Trace[3+Cos[Pi]+Sin[Pi],2,TraceBackward->True]
