Problems with GDX2HAR and HAR2GDX

GDX2HAR and HAR2GDX are programs (written originally in 2003 by Mark Horridge in collaboration with Tom Rutherford) which are designed to convert data between the GAMS GDX and GEMPACK HAR data file formats. Since that time the 2 programs have been been maintained independently (and diverged!) by GAMS and GEMPACK developers. At the same time the HAR and especially the GDX formats have evolved; an older program may be unable to read a later input file.
