From: Barry Farinet on 22 Jun 2008 11:41 In my Tcl scripts, I often use GhostScript to convert PS to PDF format. The main platform for these programs is Windows XP. The problem is that each time I install a new version of GhostScript the running directory name is modified to reflect the version number. To partially solve the problem I put the GS path into a parameter file. Is there a way (maybe through registry keys) to automatically locate the active version of GhostScript? Thanks for yours ideas.

If GhostScript is the handler for .ps files, then you can use the following: package require registry set app [registry get {HKEY_CLASSES_ROOT\.ps} {}] set cmd [registry get HKEY_CLASSES_ROOT\\$app\\shell\\open\\command {}] Cmd will contain the command string needed to open a .ps file. You will probably have to parse the result to remove switches, etc. Keith
