Visilogic Software 9.8.65 Output Coil is not getting On Even Called from Main Routine and Not been Used in program as a output coil

The most common reasons for failure of a coil to be activated are: in a subroutine that is not being called, or duplicated elsewhere in the program. You've apparently addressed those. Another possible cause is that the program you are using in VisiLogic is not identical to the program in the PLC. VisiLogic will not warn you of that problem.

A troubleshooting technique I like to use is to place an MI Increment function just after the coil. Whether or not the MI increments will help lead you to the source of the problem.
