151 : i_nLogicalOffset: an offset to be applied to each number in the string before inserting it in the resulting sequence
152 : example: a user enters page numbers from 1 to n (since that is logical)

163 : - only non-negative sequence numbers are allowed
164 : - only non-negative values in the input string are allowed
165 : - the string "-3" means the sequence i_nMinNumber to 3

168 : - single number that doesn't fit in [i_nMinNumber,i_nMaxNumber] will be ignored
