The FTP-SET.ZIP archive contains all the files needed for proper operation of the FALCOM/FTPCOM set of TSRs. This zip file includes ALL the ARMSxxxx.DAT files you should have in your ARMSDATA directory (all these and no more) ... as well as AIRVARS and INSTACT.LES files for use with the Falcon Ladder competition. In addition, a utility program is included ... SET-FALC.COM ... that can make managing the necessary files very easy. If you intend to use the SET-FALC.COM utility ... DO NOT UNZIP THE FTP-SET.ZIP ARCHIVE Instead, simply copy the FTP-SET.ZIP archive, along with the SET-FALC.COM utility to your Falcon directory. Of course, be sure to read the documentation provided for SET-FALC.
