== a graphic view of the first 10k
For those that are interested, here is the output of my '''$CALC''' (REXX) program that shows a binary map of the first 10k semiprimes.
<br><br>The command used was: (extra blanks were used to make the command's arguments easier to read)
The '''isSemiPrime''' BIF outputs a '''0''' (zero) to indicate the number isn't semi-prime, or a '''1''' (unity) to indicate a semi-prime.
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.
(Output is shown at <sup>'''2'''</sup>/<sub>3</sub> size.)
