I am creating a MAP (input using map…) with a vertical column of an array (see attachment, screenshot 4.). On the left you see the selection array for the user. What I want is for the user to place one X in any one of the boxes, and all the other boxes to turn gray, unmodifiable, so that only one box can be selected at a time.
Screenshot 1 of the attachment shows the array on the map. Screenshot 2 of the attachment shows the field #SELECT-ARR, the control variable #SEL-AD (defined as #SEL-AD (C/1:10) in define area) and the DIM as 1.
Screenshot 3 shows the layout of the array on the map (10 vertical occurrences.)
Can this be done using a map?
I am fairly new to Natural so can anyone give me some code examples or the statements I would need to use to get all the fields to turn gray except for the one with the X?
