'>statements, but the Real problem is, what if a new user
'>wants to use the game? Can someone help... I need it to
'>open the player.dat file, search for the Real Name, Load
'>The Data, And Save The Data in the right spot.... Can
'>Someone Help Me?

'   I can try. The following code uses a random access file to keep
'   scores for a BBS game. The PlayerName field is the key field
'   that the code uses to keep track of the players and their scores,
'   etc... The code also creates an SCORES.ANS file which is just an ANSI
'   high scores file that a SysOp can use on his BBS bulletin(s) menu. You
'   can modify as needed or use as a rough guide. It will reach you in
'   2 messages as it's kind of long so you will need to edit it back into
'   a single file before running it. Hope it helps. Good luck!
