TKdataSet

TKdataSet returns the VALID min and max values found in a list of numerical values.

TKdataSet differs from HyperCard's min/max in that it is faster, accomplishes both tasks simultaneously and accepts invalid data.

TKdataSet is particularly useful for scaling graphs.  You may use ANY character as a datapoint delimiter.
