Get all the values before and after a character in string
"I don't want" is a not a good explanation of the problem you have with it. How I can give you a solution that doesn't have the same problem if you tell me what the problem is? Or maybe you don't have a good reason and what needs to change is your approach.
I already suggested another solution if you don't like strSplit(): str2con().
And of course, if you have too much time, you can develop and test your own solution doing the same thing, such as with strFind() or strScan() and subStr(). See the code of strSplit() and/or str2con() to see how Microsoft did that.
