description evolves as unanticipated results materialize.
Better description of problem:
Assemble a number of different strings with the final result being a single
string of words and phases that are delimited by commas. Strip out duplicate
words or phases in the result. Singular words are allowed in the phrases.
Could not the comma be used to distinguish between words and phrases? Would
be difficult to create a dictionary of all words that may be in original
string.
Will play with both Claude's and your suggestions.
Thanks,
Doug
