Debugger handling of errors differs according to the type of error: compilation errors or request cancelling (runtime) errors.

If a program contains a compilation error, you can still use the Debugger to view the source code, along with the <var>Model 204</vvar> error messages embedded (highlighted and prefixed with ER>) after the program statements that caused them: 

[[compileerr3a1.zoom65.gif|[[File:compileerr3a1.zoom65_zoom75.gif|class=image-toggle|compileerr3a1.zoom65_zoom75]][[File:data:image/svg+xml;base64,PHN2ZyBjbGFzcz0iaW1hZ2UtdG9nZ2xlLW1hZ25pZmllciIgdmlld2JveD0iLTEgLTEgMjUgMjUiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PHBhdGggZD0iTSA5LjE0NSAxOC4yOSBjIC01LjA0MiAwIC05LjE0NSAtNC4xMDIgLTkuMTQ1IC05LjE0NSBzIDQuMTAzIC05LjE0NSA5LjE0NSAtOS4xNDUgcyA5LjE0NSA0LjEwMyA5LjE0NSA5LjE0NSBzIC00LjEwMiA5LjE0NSAtOS4xNDUgOS4xNDUgWiBtIDAgLTE1LjE2NyBjIC0zLjMyMSAwIC02LjAyMiAyLjcwMiAtNi4wMjIgNi4wMjIgcyAyLjcwMiA2LjAyMiA2LjAyMiA2LjAyMiBzIDYuMDIzIC0yLjcwMiA2LjAyMyAtNi4wMjIgcyAtMi43MDIgLTYuMDIyIC02LjAyMyAtNi4wMjIgWiBtIDkuMjYzIDEyLjQ0MyBjIC0wLjgxNyAxLjE3NiAtMS44NTIgMi4xODggLTMuMDQ2IDIuOTgxIGwgNS40NTIgNS40NTMgbCAzLjAxNCAtMy4wMTMgbCAtNS40MiAtNS40MjEgWiI+PC9wYXRoPjwvc3ZnPg==|class=image-toggle-magnifier]]]] 

As shown above, the status strip displays a Compile errors! message, and the <var>Run</var> button is the only program execution operation available. 

* You can move to the next program statement that did not compile, if any, by pressing the F11 key (by [[Default settings of buttons and hot keys|default]]), by selecting the <var>Error</var> > Next Compile Error menu item, or by using a button to which you have [[Setting up the ui.xml file#Button toggle for compilation errors|mapped]] the [[nextCompileError command|nextCompileError]] command. 
* You can move to the previous statement that did not compile, if any, by pressing the F10 key, by selecting the <var>Error</var> > Previous Compile Error menu item, or by using a button to which you have mapped the [[previousCompileError command|previousCompileError]] command. 

Clicking <var>Run</var> (or selecting <var>Error</var> > <var>Quit</var>) invokes no further operation on the code, and (if <var>Janus Debugger</var>) the Web Server sends the compilation error messages to the browser, then advances to the next program, if any. If under the <var>TN3270 Debugger</var>, the compilation error messages are sent to the terminal.

If a program contains a request cancelling (runtime) error, the Debugger lets you step through the program until you execute the statement that causes the error, or if you click <var>Run</var>, executes until the point of the error. At this point, the Client displays the source code (highlighting the line that has the error), for example:

[[File:runtimeerror78.png|1220x168px|runtimeError78]]

It also:

* Reports the values of any watched variables at the point of the error
* Reports the canceling error message in the Client's audit trail displays
* In Model 204 Version 7.8 or higher, the routine or method where the error occurred is identified.
