Need a function that uses the last element for padding rather than 0, for example,
Code: Select all
      L←8 9 3 4 5
8 9 3 4 5 0 0 0 0 0
      10 {overtake} L
8 9 3 4 5 5 5 5 5 5
8 9 3 4 5 5 5 5 5 5
Likewise for -ve overtake when it should use the first element.

I don't often need to pad with something other than the array prototype, but when I do I find it easy enough to code around. For your example I'd probably use something akin to:
Code: Select all

I do occasionally want to force a particular prototype to pad with, especially if my vector may be empty and I need it to have a particular type/depth. For that I use the alternate form:
Code: Select all
