The RTX SDK Documentation explains that applications running in the RTX subsystem must access files using a fully qualified path name. For this reason, the usual default file location rules for LayGO do not apply to LayGO for RTX. In particular, .cfg file names specified in the cfg file list to laygo32h.rtss must include a drive letter and full path. Also, a non-default service database must be specified to laygo32h.rtss with the fully qualified path of the service.db file. For details, see the chapter in the RTX SDK Documentation called File IO.
Note: These files must be located on a local drive for RTX to find them using a drive letter. They cannot be located on a locally mapped network drive.
