In the following example, if %I0001 is set, the bit string starting at %M0001 is searched until a bit
equal to 1 is found, or 6 words have been searched. Coil %Q0001 is turned on. If a bit equal to 1
is found, its location within the bit string is written to %AQ001. If %I0001 is set, bit %M0001 is 0,
and bit %M0002 is 1, then the value written to %AQ001 is 2.
