The database consists of two files, SDX_QSL.FUL and SDX_AD.FUL To use it with PacketCluster, run MAKEIDX with both Syntax: MAKEIDX SDX_QSL.FUL 70000) and setup the database definitions in your sysop.dat file I recommend using 4 different database files: QSL,SDX_QSL,AD,SDX_AD Use QSL and AD for local updates and SDX_QSL, SDX_AD for the DB0SDX database Use 6 SET/COM/CHAIN commands to have a database lookup perform in every one of the 4 databases regardless of success in finding an entry or not Make QSL the first database in the chain, with the others following The first SET/COM/CHAIN will make the system lookup in SDX_QSL if nothing was found in QSL. The second will make it lookup in SDX_QSL even though something was found in QSL! etc. etc
