2.10.5 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:
Status = GETTENV(_NAME, _TDDL)
Value/parameter:
Status
INT
0: Function OK
-1: No memory reserved for tool environments:
MD18116 $MN_MM_NUM_TOOL_ENV = 0 (number of tool environments in TO
area).
i.e. the "tool environments" functionality is not available.
-2: A tool environment with the name specified in _NAME does not exist.
_NAME
STRING
Name of the tool environment, from which the T, D and DL numbers can be read
_TDDL[3]
INT
This integer array contains:
- in "_TDDL[0]" the T number of the tool,
- in "_TDDL[1]" the D number of the tool,
- in "_TDDL[2]" the DL number of the tool,
whose tool environment in the data set is stored with the name "_NAME".
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.
