tuple_environment — Read one or more environment variables.
tuple_environment reads the content of all environment variables that are referenced by their names in the input tuple Names and returns the content with the output tuple Values. The input tuple may only contain strings.
For general information about string operations see Tuple / String Operations.
If the input tuple is empty, the operator returns an empty tuple. Additionally, an empty string is returned for every name within Names that does not denote a valid environment variable.
HDevelop provides an in-line operation for tuple_environment, which can be used in an expression in the following syntax:
Values := environment(Names)
Tuple containing name(s) of the environment variable(s).
Content of the environment variable(s).
