JIDX test Mult Check in POST

[n0dh@iea.com (DAVE - N7EX)]

When running the multiplier check on the JIDX contest logs POST wants to
treat the JA prefixture numbers as ZONES. Left to its own devices POST
would Change every JA prefixture number to Zone 45. Everything else seemed
to work fine including importing the Prefixture (AM i saying that right?)
numbers into TRMASTER.DAT USER(1) from (hint) space #55.
