Thank you all for your suggestions. I have tried using the CHR$(34) in various ways but it doesn't get interpreted properly. The Hotlink ignores the path and just looks for the "myprog.mbx" I made a command string as Greg suggested, but when it got to the Run Command line there was error. "Variable or Field C not defined" Then Tim suggested the extra quotes, and that did it perfectly, like this: SetMapString = "SET MAP layer 1 Activate Using """ + mbxname + """ On Objects Relative Path Off" You have all been very kind. Thank you! Sal
