# Contest Dupe Program

Here’s another contest dupe program, useful for eliminating duplicate contest contacts. It requires 16K duplicate and holds 1600 calls. The band variable (B$) should be two characters. The program prints the calls by call areas for each band, but does not sort the calls. Hank used a modified version of KQ2F’s Roster Program (Apr QZX) to sort. He has hopes of converting it to machine code to speed it up. I bet Bob Berch’s compiler would do the trick!
