I have always used acad.pgp as my shortcut commands.Recently I reloaded AutoCAD 10 and I cannot get it to recognize my shortcuts.How can I get AutoCAD to read the acad.pgp file.

First the path to the acad.pgp has to be valid.

If you do this:
 
(findfile "acad.pgp")
 
and it returns nil, then that file is not in one of your Support File Search Path locations.  Move it to one of those folders, or add its location to that list in Options.
 
You should probably also Search for it otherwise [e.g. via Windows Explorer], to make sure you don't have more than one such file.  If you do, I think AutoCAD will use the one in the location higher up in the SFSP list [the first one it finds], so if there's any difference, and there's some reason not to eliminate the wrong one(s), be sure the right one is in a location higher up in the list.  You can adjust the order of the list in Options.Kent Cooper2015-02-17 16:38:15
