GDINVALID, Unrecognized Global Directory file format: ffff, expected label: eeee, found: bbbb
Run Time Error: This indicates that a version of the global directory file ffff does not match with the version expected by GT.M. The file might have been created by an incompatible GT.M version. If the text of eeee or bbbb contain non-graphic characters, GT.M replaces each of them with a period (.).
Action: Compare the labels eeee and bbbb. If the global directory was created by an earlier GT.M version, upgrade the file by loading and then saving the file using the GDE of the new GT.M version.
