LOAD WINDOW
Load a window definition from a HMG window
definition file
LOAD WINDOW <WindowDefinitionFileName> [ AS <WindowName> ]
If you omit the AS clause, the window definition file name (without extension)
is assumed as the window name.
A HMG window definition file ('.fmg' file) is a text file containing a window
definition, using standard HMG code, except the window name in the
DEFINE WINDOW command (you must use TEMPLATE word instead).
