While recording, the AtcgRecordApp application writes code fragments and diagnostic information to rrmsg<nn>.log. This is a versioned JADE log file, which is rolled over each time it starts recording. All historical rrmsg logs are archived in the logs folder in case they are needed later; for example, for problem resolution.
When recording is started, form references are generated for all loaded forms, in case you decide to use them. Other form references are generated during capture of the preamble of the form's load method. In addition to the form reference itself, an application getForm method call is generated, to retrieve the form object identifier (oid) at replay time.
Most of the information written to the rrmsg log is written by the AtcgControl class capture method when operating under the tested application and method tracking.
