Read T, D, DL from a tool environment

GETTENV function
The GETTENV function is used to read the T, D and DL numbers stored in a tool
environment.
The GETTENV function is a predefined subprogram. It must, therefore, be programmed in a
separate block.
Syntax:
Value/parameter:
Status
_NAME
_TDDL[3]
It is possible to omit the first parameter in the GETTENV function call (e.g., GETTENV(,
_TDDL)) or to pass a null string as the first parameter (e.g., GETTENV("", _TDDL)). In both
of these two special cases, the T, D and DL numbers of the active tool are returned in
_TDDL.
Basic logic functions: Tool Offset (W1)
