In field correct mode, the checks are made as in enter mode. If the checks aresuccessful, the field is blanked on the screen, the cursor moves to the first pmitionof the field, and the mode returns to verify mode. The field can then be verified.In verify mode, the ~I (Field Advance) key is valid only after a constant insertverify error or when the system is awaiting field exit or record advance. If awaitingrecord advance or field exit, the field advance key is processed as for entermode except that the attribute checks are ignored. If the ~I (Field Advance) keyis pressed after a constant insert verify error has occurred, after the operator haspressed the Reset key the constant in the current record buffer remains unchangedand a field advance is performed.Field Backspace FunctionThe field backspace function is initiated when the operator presses the I+- (FieldBackspace) key, and is valid only when an ENTR command is being processed.In enter, update, and special verify modes, if a I+- (Field Backspace) key is pressedwhile the system is awaiting the field-exit or record advance, the condition iscleared and the cursor is repositioned to the first position of the field.If the I+- (Field Backspace) key is pressed when the cursor is in any field positionother than the first position of the field, the cursor is repositioned to the firstposition of the field.If the I+- (Field Backspace) key is pressed when the cursor is in the first positionof the field, the cursor is repositioned to the first position of the preceding inputfield. Intervening automatic fields, prompts, and display attributes are ignored.Intervening RG (return to program) exit specifications are posted with the externalstatus condition 5. If the mode is special verify, the data field in which the cursorwas positioned when the key was pressed is blanked, and intervening automaticfields are blanked.If the I+- (Field Backspace) key is pressed when the cursor is in the first positionof the record, format specifications between the first position and the start of thescreen format are processed in the backward direction, then in the forward direction.A record backspace is not performed.If the field definition specifies format level zero, the field backspace is processedas a +- (Character Backspace) key.In field correct mode, if the system is awaiting field exit, the I+- (Field Backspace)key is processed as descri bed for enter mode.If the I+- (Field Backspace) key is pressed when the cursor is in any position otherthan the first position, the key is processed as described for enter mode. If the keyis pressed when the cursor is in the first position of the field or of the record, thekey is processed as described for enter mode except that the entire field is blankedon the screen and the mode returns to verify mode.In verify mode, jf the I+- (Field Backspace) key is pressed while the system is await·ing field exit or record advance in a right-to-Ieft field, the condition is cleared, thefield is blanked on the screen, the cursor remains in the rightmost position of thefield and the entire field must be reverified.Keyboard Functions 325
