GDUNKNFMT, xxxx is not formatted as a global directory

GDE Information: This indicates that GDE could not load the specified file xxxx because it is not a valid Global Directory file. GDE aborts the load after it issues this message.

Action: Verify that the file is valid and look for typographical errors. Something other than GT.M or its utilities may have written to the Global Directory file or created a file with a name that coincides with the one specified by GTM$GBLDIR / gtmgbldir.
