Fetches the specified environment variable and includes it in a new attribute.

Environment variables are convenient especially if certain standard folders and parameters need to be referenced in a workspace, but the actual locations or names can vary from computer to computer.

The available variables will depend on which platform you are using. For example in Windows you can find a list of variables on your system by opening Control Panel > System > Advanced > Environment Variables.


Usage Notes

Within an FME workspace you could use the value retrieved to:

  • Define the output location of a dataset (in conjunction with Feature Type Fanout, which is described in the Workbench help files)
  • Define the location of a file for the AttributeFileWriter or AttributeFileReader
  • Define the location of a workspace to run with the WorkspaceRunner
  • Write the value to some type of metadata output

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
