Program Question

Using help that I have received in this great NG, I have been able to write a program that does ALMOST what I want to do. But I am asking
the community to take a look at it and see one thing for me. Here is the program (the notes I put in there after the ; are for my employees to learn, I am assuming most people in here might know what those codes meant already, but I left them in there in case)
The two questions I have are 1. For some reason the coolant is only coming on for the SECOND operation/subroutine. Now when I look at the program, it seems my m08 code is in the FIRST operation and NOT in the second, but yet it is not turning on until after I have switched to the 1 tool. Can anyone see why this might be happening? 2. I am trying to drill these holes to Z-.06 and Z-.105 deep using the mill and drill respectively. It seems that in this program it is moving the tool -.06 and -.105 from the ORINGINAL Z starting point of Z.04 (which I have just for a clearance), meaning it seems its doing an incremental move of .06. What I need it to do is come to an ABSOLUTE point of Z-.06. Is there something that I am doing wrong here? (like should there be a g90/91 switch somewhere)?

I don't know the answers but have two suggestions -- 1, crosspost to alt.machines.cnc instead (or only); 2, specify what machine and controller you have, since some M codes can be machine specific. -jiw
