Trace Statements
A Trace Statement is a message that is output during execution of a debug session. Trace statements can be defined in Enterprise Architect without requiring any changes to your application source code.
Tracepoint Markers are set in the code editor. Like breakpoints, they are placed on a line of code. When that line of code executes, the debugger evaluates the statement, the result of which is logged to the Debug window. (or to file if overridden by the Analyzer script)
Access
Any existing Trace statements can be viewed and managed in the Breakpoints & Markers window. The Breakpoints & Markers window can be displayed using either of the methods outlined here.

Specifying a Trace Statement
A trace statement can be any freeform text. The value of any variables currently in scope can also be included in a trace statement by prefixing the variable name with a special token. The available tokens are:
- $ - when the variable is to be interpreted as a string
- @ - when the variable is a primitive type (int, double, char)
Using the example in the image above, we could output the number of people getting off a train by using this statement:
There were @Passengers before @PeopleOFF got off the train at $Arriving.Name Station
