zonsui is a system variable that can be assigned during a control called during an input in a mask in order to change the order of input by reassigning the next field to be inputted.

This function is only usable in Classic pages related code and is deprecated for code running in version 7 mode.

Description

zonsui is an alphanumeric variable that contains the next field to be inputted (if not empty). By default, it contains the empty string "" when the control, init or help label is reached. When the value is empty, the next field in the mask order is accessed.

Comments

• If zonsui contains a field name that cannot be entered, the first following enterable field will be accessed.

• zonsui can set the next field in another mask or on another rank.

• If during an input check validation of a field has to be prevented, without sending a "beep" to the screen, simply assign to zonsui the name of the current field on which the check is made. This may be done by assignment, for non-dimensioned zones:

zonsui = zoncou

• If the field belongs to an array, you can write:zonsui = zoncou+"(" + num$(index) + ")"
• Setting mkstat to 2 will have the same effect.
