Thankyou MiniMax, I assume that I could include all of the setup commands in the autoexec portion of the config file, and then issue a DosBox -c "name argument" comand? I noticed that you used nested quoutes in your example. Is that to account for the possibility of embeded blanks in the file path …

Evidently I need to elaborate on what I'm trying to do. I have a spreadsheet that contains a macro which uses the Visual Basis shell() function to run an external program. That program is passed a file name argument obtained from the spreadsheet cell that has the focus when the macro is run. Works …

This must be either very obvious or impossible. How do I pass a command line argument to a program? Something like dosbox edit -thisfile.txt Larry
