Why doesn't the error appear in the dump file?
 You need to make a caller to MrdSaveErr(oError)
──────────────────────────────────────────────────────────────────────────────

 This is because you haven't give MrDebug thre ability to capture the error.

 To enable MrDebug to capture an error object from your application and
 display it in an error window, where you may browse and edit the object, add
 the following line to your error system:

                MrdSaveErr(oError)

 This will allow MrDebug to save any error, if it occurs, and display it in
 an Error Window. You may then select this window, if not already selected,
 and press ◄──┛ to display further details of the error object.
