*** 89 IF X COMPARED TO F ***
FUNCTION
This instruction compares an input location to a
fixed value and, if the result is true, performs
the specified Command. The comparison codes
are given in Table 12-5.

*** 90 STEP LOOP INDEX ***
FUNCTION
When used within a Loop (Instruction 87),
Instruction 90 will increment the index counter
by a specified amount after the first time through
the loop, thus affecting all indexed input location
parameters in subsequent instructions within the
loop. For example, if 4 is specified, the index
counter will count up by 4 (0, 4, 8, 12,...) inside
