Mazak Matrix2 i630v Integrex - Macro Variable List

I am searching for a EIA Macro Variable Listing, in general, for Mazak / Matrix2 / Integrex / i630v. (Future Usage)
Specifically, the variable for the pre-call tool number in the standby pocket.
I know that #3020 will give me the current Spindle Tool.

We have the option for Tool Breakage Detection Outside the Machining Area (M55/M56).

The procedure call by the book is:
T01 (First Tool)
M06
(TOOL PATH)
(END OF TOOL PATH)
T02 (Pre-Call Next Tool - Standby Pocket)
M55 (or M56) (Check For Breakage T01)
M06 (Load T02 - Place T01 in Standby Pocket For Breakage Detection)

In my programs, I typically pre-call the next tool in the same line as my original tool call/tool change.
ie. "T01 M06 T02"

I am not sure there is a need to pre-call the next tool a second time, before the M55/M56 command.
But if it is necessary, I want to keep my normal tool change/pre-call before the path, and then make the second pre-call using a variable (tool loaded in standby pocket).
That way, if for some reason the original pre-call number is changed, it will not be missed at the second pre-call, before the M55/M56.

TIA!
