To read the Error number on VFP Help.

At VFP Help, Click 'Content' Tab.
Select 'Techical...' and then select 'Error Message'... 'Error Number'

In my mind, Some Error number will often come...
5 - out of range error
1884 - Primary Key Conflict
1592 - Object not found
1585 - Fail to lock the Record!

P.s. I also complain that there is not enough ways to help the programmer to
overcome the error in error number help section.
It is one of the part which waste programmer to find method to do...
if some positive suggestion is given, it will save much of time!!
