You can create your own form/window that the browse is IN on the fly. I do this for report preview. Browse has a IN WINDOW option, look at the help system for details. Look at the code below and see how I do it for a report preview, you can easily change the code to show a browse window. As for the expression, if you create the file with SQL select, then there is an AS option that can be used. Look in the help system for using the AS clause.
