Question
Sir,
instead of entering a command (ex: Line), we can enter simply "l".
But sometime it is not taking that shortform of that command, so we have to type the command fully, I want to know the reason for this problem,.. and i want to overcome the problem,.. please help me sir,..

Answer
Sarvenkatg:
When this happens, the first thing you need to know is that if ACAD.PGP is in the Support File Search Path.  To find that out, type the following at the command line:
(findfile "acad.pgp")
AutoCAD should return something like this:
"C:\\Documents and Settings\\Bill\\Application Data\\Autodesk\\ADT 2006\\enu\\support\\acad.pgp"
If it does, then type REINIT to initialize the PGP file.  Look at the command line to see if it reports errors from the PGP file and on what line number.  If AutocAD returns nil when you type in the code, then something bad has happened to your AutoCAD setup and probably needs to be reinstalled.  You can do a repair installation with your original installation disk in your control panel - Add/Remove Programs (or just Programs).  Their should not be a need to completely remove and reinstall AutoCAD.  An installation repair should do the job.  Another thing that can cause the problem:  When AutoCAD is loading, if the user hits ESCape to make the process of launching AutoCAD go faster, he or she can prevent the loading of ACAD.PGP and the command aliases will not work.

Let me know how it goes.
