# Control on a grid (this label can be called on any field of the grid
# If there is an error, return to the previous line on the same field.

    zonsui = zoncou+"(" + num$(max(nolign-2,0)) + ")"
  Endif
End

Description

zoncou is an alphanumeric variable that contains the name of the current field inputted. It is available on any control, init or help action.

Comments

zoncou does not contain the current index on arrays. indice (0-based) or nolign (1-based) can give this information.

• 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 by using zoncou:

zonsui = zoncou

• If the field belongs to an array, you can write: zonsui = zoncou+"(" + num$(index) + ")"
