!f the I+- (Field Backspace) key is pressed under any other condition. the key isprocessed as described for enter mode except that any data character that is backspacedover is blanked on the screen, and reverification is required in order toadvance over the position.If the field definition specifies a format level zero, the I+- (Field Backspace) keyis processed as for al+- (Character Backspace) key.Field Correct FunctionThe field correct function is initiated when the operator presses the lowercaseField Corr (Field Correct) key, and is valid only in verify mode. It is not validfor a format level zero field.If the Field Corr key is pressed when the cursor is in an automatic field, verification<strong>of</strong> the field is not done automatically.When the Field Corr key is pressed and a constant insert verify error has not occurred,the cursor is repositioned at the first input position <strong>of</strong> the current field andthe field is filled with blanks in the current record buffer and on the screen. Theoperator can enter data into the field as in enter mode. Auto dup and auto skipfunctions are not performed. Character set and field edit checks are performed.When the field is exited in the forward direction, the cursor is repositioned to thefirst position and the mode returns to verify mode.Following a constant insert verify error, the operator can press the Reset key, thenpress the Field Corr key. The constant insert data from the main storage locationspecified in the screen format is placed into the current record buffer. This dataoverwrites the data in the buffer. A field advance is then performed.Field Exit FunctionThe field exit function is initiated when the operator presses the Field Exit or theField+ key, and is valid only when an ENTR command is being processed.In enter, update, special verify, and field correct modes, if the key is pressedwhile the system is awaiting field exit, the awaiting field exit condition is clearedand a field advance is performed. If the key is pressed while the system is awaitingrecord advance, an error occurs unless the auto-enter flag is on. If the auto-enterflag is on, a record advance is performed.• Right-Adjust Field: For a right-adjust field (that is not signed numeric), theright-adjust function is performed before the field advance occurs. The datain the field to the left <strong>of</strong> the cursor is right-adjusted on the screen and in thecurrent record buffer. The leftmost positions are filled with alphabetic ornumeric fill characters, according to the field definition. The zone <strong>of</strong> therightmost byte in the buffer is not changed. If the key is pressed when thecursor is in the leftmost position <strong>of</strong> the field, the entire field is filled with thefill characters.326
