what is the difference between special and pair

Hi Muthyala

Special and pair value sets provide a mechanism to allow a "flexfield-within-a-flexfield". These value sets are primarily used for Standard Request Submission parameters. You do not generally use these value sets for normal flexfield segments. Special and Pair value sets use special validation routines you define. For example, you can define validation routines to provide another flexfield as a value set for a single segment or to provide a range flexfield as a value set for a pair of segments.

In short
Special ------values set uses a flex field itself
Pair ------ two flex fields together specify a range of valid values.


I could find this after doing a little bit of searching.
