OK. Today I'm working on a prototype GUI for a medical setting ( the production GUI will be done in C++, I believe). The GUI must keep track of a patient's name, prescriptions, and diagnoses, as well as things like what treatment room the patient will be seen in. Because different treatment rooms have different equipment, and so are used for different purposes, the user of the GUI will begin by selecting a treatment room, which pulls up from the DB all the patients scheduled for that room on that day. There are 6 treatment rooms, and if a user has navigated 3 or 4 steps into the GUI then decides to select a different treatment room ( and a different patient ), then everything gets reset. Most of these variables are getting stored as session variables so that the data persists as the user navigates further into the application. Including things like username, password, permissions, login flag, database, hostname, patientID, prescriptionID(s), diagnoses, treatment room, and several other variables, I'm using about 15 session variables. As I debug, I'm needing to sort through a growing number of variables to see what values have been stored in them. This is getting tedious because the list scrolls off the page. But as I develop more of the app, the need for more persisting variables has grown, and I guess I just had a moment of panic that I was gonna hit some limit of persisting variables. BTW, this GUI is for an intranet site, with perhaps 20 users max. You've been extremely helpful to me and many other listers here, John, and I did not mean to perturb you in any way by my initial question. David
