User Input Error Checking
When users type data and press the ENTER key, errors are sometimes
detected by the terminal.IBM display stations and HP terminals process
errors differently. The following list summarizes these differences:
* HP terminals perform input-data error checking after the user
presses the ENTER key or a valid function (AID) key.
* If multiple input errors are detected in more than one field, Pass
Thru reports one error at a time starting with the first
occurrence.
* Error messages are displayed at the bottom of the screen.
* The cursor is positioned at the beginning of the erroneous field.
* The erroneous field is redisplayed with the user's input data.
