Command GUIPANEL allows to associate an help file to the
main window or detached menus, and command GUI
BUTTON does
the same for optional windows.
The HELP files format should be
1 Description General help for the window or menu 2 NAME1 help for variable NAME1 2 NAME2 help for variable NAME2 1 ENDOFHELPwhere 1 and 2 are in the first column of the text file, and followed by a single space.
Clicking on the HELP button will display the complete help file in a scrolled window. Clicking in the prompt area of an input variable will display the associated variable name and the help for this variable (if it exists).
