Unfortunately, no, and I'll try to illustrate why. But thanks for the 
response!

strtok("afoobfooc", "foo") does return ["a","b","c"] as asked but so do 
the following:

strtok ("afoooooobfooc", "foo")
strtok ("afbfooc",       "foo")
strtok ("afobfooc",      "foo")
strtok ("afoofbfooc",    "foo")
strtok ("aofobfooc",     "foo")

which is not the same the substring-based chopping I initially asked 
about. According to what I initially asked about:

strchop ("afoooooobfooc", "foo", 0)

should return a 7-cell string array:

["a","o","o","o","o","b","c"]

because "foo" is the indicator of the chopping point. "foo" is not the 
same as "foooooo" but both list the same set of characters -- "f" and 
"o" which means strtok() is behaving as 
http://www.jedsoft.org/slang/doc/html/slangfun-5.html#strtok describes.

Thinking about this beyond what I initially asked about, it might be 
more useful still to have a function where one could use a regular 
expression as a chopping point instead of a substring.
