Protected: Data cannot be entered in a protected field. If the operator attempts to enter data, the keyboard is locked. Stopper fields that follow variable-length data fields are normally defined with protected attribute characters. If the operator attempts to enter more characters than the variable-length data field can contain, the stopper field that follows it causes the keyboard to be locked.
Autoskip: An autoskip field is a protected field that automatically skips the cursor to the next unprotected field. Keyword fields and stopper fields that follow fixed-length data fields are normally defined with autoskip attribute characters.
