SYSOP.EXE --------- The SYSOP program is used to import host mode CTL files from the old 14.03 format to the 15.00 format. The program also contains several other useful options. Especially interesting is the option to construct an index file for the user file. If the index file on the main user file becomes corrupted, this option will fix it. The SYSOP program is also used to maintain user records, raise access levels, delete old users and produce user and message base listings.
