18.12.4 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.
$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.
18.12.5 Read T, D, DL from a tool environment
GETTENV function

INT
Number of defined TOOLENV
Syntax:
_NAME = $P_TOOLENV[i]
Data type:

i
