Hi,
thanks for the answer. The method 2 nearly worked for me, I settled with the
following solution:
data-block: ["Wilhelm" "Helge" "Werner" "Fritz"]
selection: make block! 100
view layout [
text-list data data-block [
change head tl2/data pick data-block index? find data-block value
show tl2
]
tl2: text-list selection
]
Interesting is the line with the change. Append does work too, but the list
gets always longer.
