Arithmetics in code

[tummen]

The default TNC drill cycle is this (shortened):
[DELETE][BLKNUM] CYCL DEF[CYCL-CODE][CYCL-DESC] [CONTINUATION]
[<C>ZDEPTH][SEMICOLON]DEPTH [CONTINUATION]
[<C>Z-LEVEL][SEMICOLON]SURFACE COORDINATE [CONTINUATION]

But in this output i get Z-Level = z coordinate of hole and
And ZDepth = botom coordinate of hole.

But my Heidenhein 426 wants the drill depth.

How can i output [ZDEPTH]-[Z-LEVEL]?

Gaaaah.

ofcourse since i asked here i found a solution finally...

;CODE: #USER1=#ZLEVEL-#ZDEPTHOUT
[DELETE][BLKNUM] CYCL DEF[CYCL-CODE][CYCL-DESC] [CONTINUATION]
Q201=[<C>USER-1][SEMICOLON]DEPTH [CONTINUATION]
[<C>Z-LEVEL][SEMICOLON]SURFACE COORDINATE [CONTINUATION]

I will leave this thread since it might be some helpe to someone but after solving how to get this to work i now realize that all i should have done was to change Hole cycle setting - Cycle Z depth to "incremental signed"
and all was fixed...
