(getenv [var_name] [ini_section] [ini_file])
The getenv function retrieves a string value assigned to a list containing the environment variables as found in the [CAD Path] section of an INI file. For example:
var_name specifies the identifier (profile name) of the variable to be retrieved.
ini_section specifies the identifier (name) of a section of the specified INI file.
ini_file specifies the complete name of the INI file (including drive and path).
The function returns a string containing the environment setting if it succeeds. It returns nil if it fails. If the getenv function is utilized without arguments, it returns a dotted pair list containing the settings of the system paths and system files as defined in the application INI file.
