Command restrictions related to PROFILE execution

During its initialization phase, IDF loads the target program, loads any symbol definitions from the MAP file or load module, and initializes its screen driver. Whether or not these events have occurred determines whether some IDF commands may be issued. The target program and its symbols can be loaded from within the PROFILE by means of the LOAD command; if this is not done explicitly, it is done automatically by IDF after the PROFILE has completed. The screen driver is not initialized until after the PROFILE has completed.

The following commands may only be issued before the target program and associated symbols are loaded:

- SET LIBE fn/$
