Precautions

Example: The following example will move #0200 to D00200 if D00100 con-
tains #0010 and move #0300 to D00300 if D00100 does not contain #0010.
The Equals Flag will turn ON if D00100 in the rung above contains #0010.
#0200 will be moved to D00200 for instruction (1), but then the Equals Flag
will be turned OFF because the #0200 source data is not 0000 Hex. The MOV
instruction at (2) will then be executed and #0300 will be moved to D0300. A
rung will therefore have to be inserted as shown below to prevent execution
results for the first MOVE instruction from being picked up.
