EHLLAPI 3270 Emulation Windowing Functions Under OS/2 Extended Edition

       Disclosed is an addition to the Emulation High Level
Language Application Programming Interface (EHLLAPI) product to allow
applications to query and/or manipulate the windows containing the
3270 emulation session running under OS/2 Extended Edition.

      Six additional functions to EHLLAPI have been disclosed to
allow a programmed interface to query or change a 3270 emulation
window size, position, visibility, relative placement to other
windows, name, and switch list entry text.  Invocation of the
additional functions is compatible with functions currently available
through EHLLAPI.  Control of access to these functions, through a
prerequisite EHLLAPI Connect to Presentation Manager Services calls,
prevents collision of two applications trying to concurrently
manipulate the same window.

      The availability of these functions allow an application to
adjust elements of a 3270 emulation session window to control and
improve its visibility to the user.
