Windows only.
Under Windows, the Session Caption displays information such as the name of the current workspace. The contents of the Caption can be modified: see Window Captions in the Installation and Configuration Guide for more details.
However, the Caption is updated only at the six-space prompt; calling ⎕LOAD for example from within a function will not result in the Caption being updated at the end of the ⎕LOAD.
This I-Beam causes the Session Caption to be updated (flushed) when called. Note that this I-Beam does not alter the contents of the Caption.
