This uic contains the modifications which I made to FDT to get it working on RSX11M V4.0. The TRACE program was modified to take into account the changes to the task builder map, and FDT was modified to allow F77 character string variables. The files FDT.VAT and TRACE.VTN are the 'virgin' files from the Spring 82 DECUS tape; FDT.MAC and TRACE.FTN are the modified files. The two .CMP files list the changes made to these two programs. I also changed the documentation to reflect the changes -- the new documentation file is FDT.RNO. GBLREF=ZCI$ was also added to FDTRSX.TKB. Read README.DOC for more information concerning FDT in general. Frank Keefer NASA/GSFC Bldg 21, Room G-39 Greenbelt MD 20771 (301) 344-5419
