Thanks a JC> lot!!! } Program RegCode; Uses Crt; Var ch : Char; Name : String; Function MakeRegCode(S:String): LongInt; Var I: LongInt; B: Byte; begin I:=0; { Could make this something else if you want it more random looking } For B:=1 to Length(S) Do I:=I+ord(S[B]); { Could make it ord(S[B]+SomeValue) to make it more interesting } MakeRegCode:=I; end; begin Writeln; Writeln; Write('Enter SysOp Name : '); Readln(Name); Writeln; Writeln('The resultant code was ',MakeRegCode(Name)); Writeln; ch:=ReadKey; end. {You can also add a BBS Name or a City or anything else you want. just keep on adding it to the I Var in the MakeRegCode proc. to check to see if a reg code is valid, just Compare the registration code he already has (in a cfg File comewhere I assume) With the one generated this part of code. if they match, then is is a good code... if not... then he didn't register. }
