Internal T number of the tool (optional).
<T>:
Data type:
If this parameter is not specified or if its value is "0", then the tool stored in <Stat>
is used.
If the value of this parameter is "-1", then the T number of the active tool is used.
It is also possible to explicitly specify the number of the active tool.
Note:
If <Stat> is not specified, the actual status is used as the tool environment. Since
<T> = 0 refers to the T number saved in the tool environment, the active tool is used
in this environment, i.e. parameters <T> = 0 and <T> = -1 have the same meaning
in this special case.
Cutting edge of the tool (optional).
<D>:
Data type:
If this parameter is not specified, or if its value is "0", then the D number used is
based on the source of the T number. If the T number from the tool environment is
used, then the D number of the tool environment is also read, otherwise the D
number of the currently active tool is read.
Number of the offset dependent on the location (optional).
<DL>:
Data type:
If this parameter is not specified, then the DL number used is based on the source
of the T number. If the T number from the tool environment is used, then the D
number of the tool environment is also read, otherwise the D number of the cur‐
rently active tool is read.

Calculates the tool length of the currently active
tool in the machine coordinate system allowing for
all components.
Calculates the tool length for the active tool, con‐
sisting of the adapter or tool base dimension, ge‐
ometry and wear. Further components, such as
toolholder with orientation capability or kinematic
transformation, are not considered. Output in the
workpiece coordinate system.
Calculates the complete tool length of the active
tool without allowing for the length components of
a possibly active kinematic transformation. Output
in the basic coordinate system.
Calculates the complete tool length in the machine
coordinate system for the tool stored in the tool
environment named "Testenv1". However, the cal‐
culation is performed for cutting edge number D3,
regardless of the cutting edge number stored.
