something i had from a while back
#! rmsubstr
∇rs←substr rmsubstr string ⍝ " " quotes required for all strings and substrings
⍝ test variables - names for ease in testing
s1←string1←"abcdefghijkcdecef"
s2←string2←"abcdefghijkcdecefa"
s3←string3←"a"⍝ single element string
ss1←substr1←"
How about
{⊃,/(¯1+↑⍴⍺)↓¨(~⍺⍷⍵)⊂⍵←⍺,⍵}
It doesn't rely on ⎕IO setting.

This is a bit simpler and fixes the empty result problem, and returns a
non-enclosed result:
RemoveSubstrings ← {⍵/⍨ ~⊃∨/ (-⍳⍴⍺) ∘.⌽ ⊂⍺⍷⍵}
Like your solution this only works with ⎕IO←0.

In a discussion on the #lisp IRC channel recently, someone wanted to remove
a certain substring from a larger string. In Lisp, the solution is to
simply use cl-ppcre and remove by regex.
But, I started thinking about how to do this in APL, and this is what I
came up with:
RemoveSubstrings ←
