A workspace is a directory that contains project directories, metadata about the contained projects, and information about the state of the IDL Workbench.
When the IDL Workbench starts, creates a default workspace located in your home directory (as defined by the $HOME environment variable on UNIX-like platforms and in Documents and Settings\username on Windows platforms).
If you later want to change workspaces, do one of the following:
Each workspace “remembers” the arrangement of the IDL Workbench views and perspectives. You can have as many different workspaces as you like, but only one workspace can be loaded at once.
