| The packing algorithm works like this, a widget of a higher packing
order gets the available space first. Followng this rule, you may
choose a packing order for a list of widgets such that some are always
visible.
Try
# packing main window
pack .status -side bottom
pack .menuber .fl .pnd -side top
# packing pane window
pack .pnd.check -expand 1 -fill x -side bottom
pack .pnd.text -expand 1 -fill y -side right
pack .pnd.canv -expand 1 -fill both -side right
Now you should have an expansible pane with a status bar at bottom and
a menubar at top. In side the pane window, the canvas is expansible in
both xy and text in y.
If you are using a Tk PANE widget, .pnd.text and .pnd.canv will be
packed in left and right pane respectively, and theie sizes will be
managered by the PANE widget. You only need to pack the pane and
checktext which should be packed first at the bottom of the pane frame.
For the second question, you may choose to use global variables, which
always work fine. You may also choose to use upvar or namespace that
will work too. My choice is to use global variables because of the
simplicity.
