Hi Petr
I will leave your first puzzle about 'change for someone else to elaborate.
There are various ways to write to an indexed element. For your example,
the following is the fastest and also fairly easy to read:
>> ar: array/initial [3 4] copy ""
== [["" "" "" ""] ["" "" "" ""] ["" "" "" ""]]
>> i: 2 j: 3
== 3
>> poke pick ar i j "hello"
== ["" "" "hello" ""]
>> ar
== [["" "" "" ""] ["" "" "hello" ""] ["" "" "" ""]]
Hope this helps
Larry
