trace.on(on=T) std.trace() std.xtrace() sys.trace()
sys.trace returns a vector of character strings naming the
functions currently being traced.
std.trace and
std.xtrace print the call made to the function being traced.
trace.on controls whether tracing is on or off by means of the
.Traceon
object in the session database.
Functions
std.trace and
std.xtrace are the default
tracer functions used by
trace on entry and exit to the traced function.
These standard minimal trace functions just print a message describing
the call.
You can use these functions as models to create your own tracing functions.
