{{PageDescription}}
|
|
* The {{Parameter|stringExpression$}} must include the environmental parameter ID and the setting:
|
|
** Using an '''=''' sign: [[ENVIRON]] "parameterID=setting"
|
|
** Using a space: [[ENVIRON]] "parameterID setting"
|
|
* If the parameter ID did not previously exist in the environmental string table, it is appended to the end of the table.
|
|
* If a parameter ID did exist, it is deleted and the new value is appended to end of the list.
|
|
* The [[_ENVIRONCOUNT]] function returns the number of key/value pairs that currently exist.
|
|
* Any changes made at runtime are discarded when your program ends.
