Help with command

Anyone tell me what command I can use to hold motor at position after home index and subroutine execution.

My program will start by homing to index to get me a repetative starting point. After homing I want the motor to hold position while I check the status of 2 inputs.Input status will send the program into three possible sub routines one will jog the motor clockwise a designated amount and the other will jog the motor counterclockwise a designated amount and one will hold present position.

The program will than continually monitor the inputs for any future move commands. If powered down unit will home again upon activation.

I have attached program . subroutines function but motor cycles back and forth constantly when running program.

Anyone point me in the right direction. Thanks Kent
