2.10.4 How many environments and which ones are saved?
$P_TOOLENVN
This system variable returns the number of available data sets for describing tool
environments. (Data sets defined by TOOLENV and not yet deleted.)
The value range is from 0 to machine data:
MD18116 $MN_MM_NUM_TOOL_ENV (number of tool environments in TO area).
This system variable can be accessed even if no tool environments are possible (MD18116
= 0). In this case, the return value is 0.
Syntax:
_N = $P_TOOLENVN
Data type:
_N
INT
Number of defined TOOLENV
$P_TOOLENV
This system variable returns the number of the nth data set for describing a tool
environment.
The assignment of numbers to data sets is not fixed, but can be changed as a result of
deleting or creating data sets. The data sets are numbered internally. The range is from 1 to
$P_TOOLENVN.
Syntax:
_NAME = $P_TOOLENV[i]
Data type:
_NAME
STRING
Name of the data set with number i
i
INT
Number of the data set.
If an index is specified, which does not point to a defined data set, the following alarm is
output:
Alarm "17020 (inadmissible array-index1)"
