processing a string by Excel

Norm,
Thanks for your help.
I have added three more examples of string in the file attached (Book111.xls). The first three are the same as in Book11.xls. But I changed them so that parameters have brackets instead of paranthesis.
Strings from A4 to A6 are new.
I have noticed that the parameters in the string A1 have extra characters after a closing bracket "]" while all the parameters in the strings in A2 and A3 end with a bracket. I have a hunch that if you add to the program the intelligence that it ignores rest of the parameter until the next space once it detects a closing bracket, it would work just fine.
Thanks.

Mark
