An alternative (from hans-peter sorge from this list, april 13, 2016).
Careful though, this does have some edge conditions which will bite:
⍝replace <old> with <new> (<o> is 2 elements) in string <s>
⍝.k text-editing
⍝.n hans-peter sorge
⍝.t 2016.4.13.0.0.0
⍝.v 1.0 / 13apr16
r←((0=⍴z)/a),z←∊((e×⍴v)↑¨⊂v),¨((⍴u)×e←+/¨(1+p)⊂p)↓¨(1++\p←u⍷a)⊂a←s⊣(u
v)←o
