What happens here is I am selecting a popup menu item and that selection sends me to one of 5 functions. Each function opens the file in the same way. I put in code for a different menu selection and checked gVolRefNum% and then compared it to gVolRefNum% in the bad section. It is the same in both, just before the call to OPEN. I know this worked before in an earlier version of the program but now is not. I am stuck. Thanks for the help. If you have any other ideas they will be appreciated. Mark
