Line 23: :::I don't agree with "The use of any phrase (or word) that is under contention (disagreement) should never be used in a definition".

The     '''translate'''       BIF converts (for easier perusing) ones and zeroes to   ■   and   <b> · </b>     [the square bullets are the semi-primes]. The         '''iota'''            BIF generates the numbers   1 ──► 10,000   which are passed to the   '''isSemiPrime'''   BIF. The      '''SQUISH'''         option removes all blanks from the output   (except for the index). The      '''GROUP'''         option groups  '''100'''   output items per line.
