Set Coordinates Tcl

I'm really starting to have fun with this.

Questions about the Set Coordinates Tcl in the 801bin.

1. What do I need to change to get the cursor to the end of the zeros
(0.0000) rather than at the beginning?

2. What other parameters can I use (it starts with 5221) and where in the
tcl do I make the change? I tried changing the 5221 at the end of the
program to 1000, but the tcl wouldn't work. I need to make a Tcl to input
data into the variable table.

3. I have changed the setaxis to "2" instead of to read from the .ini file.
I labeled them "Shim Adjust" and Excessive Wear" which I need to correspond
to axis X and A. X is working OK, but I the 2nd axis (A) is updating the Y
field. What do I need to do to change that?

4. Where does the data come from that the Tkemc reads when it displays the
axis offsets? I can't figure out why when I enter in 1.0 on the
Set_Coordinates the display changes by .0394. I'm using G20 (I think) and
the .ini file has been changed from "auto" to "inches"

Thanks.
