The owner of a small computer store was getting tired of fixing the exact same problem over and over on computers for people...one day 3 customers came in at the same time.

He looked at them all and said.
Everyone one of your computers gave me this error message
"Error you have a syntax IDtenT error.and asked them to right it down.

All of them got out their pens and wrote IDtenT error, he smiled then told them.

No that's not how you write it is the number "10".
So they all wrote it again...ID10T error
