|Is it possible to write a .twmrc that can be used with both X11R3 and
|X11R4?  Not all of our systems here have been upgraded to R4 yet.  The
|problem seems to be that the R4 version of twm requires vertical bars
|between modifiers in mouse bindings, while R3 doesn't like them at all.

Use colons between the statements, as follows:

-- cut here --
#Button = KEYS : CONTEXT : FUNCTION
#----------------------------------

Button1 =      : title   : f.raise
Button1 =  m   : title   : f.raise
Button1 =  m   : window  : f.raise
Button1 =      : icon    : f.iconify
Button1 =  m   : icon    : f.iconify

Button2 =      : title   : f.move
Button2 =  m   : title   : f.move
Button2 =  m   : window  : f.move
Button2 =      : icon    : f.move
Button2 =  m   : icon    : f.move

Button3 =      : root    : f.menu "programs"
Button3 =  m   : root    : f.menu "programs"

Button3 =      : title   : f.menu "window"
Button3 =  m   : title   : f.menu "window"
Button3 =  m   : window  : f.menu "window"
-- cut here --

There are some incompatibilities (eg "AutoRelativeResize" doesn't
exist in the R3 version) but for the most part they're pretty close.
I do wish twm would ignore keywords it didn't recognize instead of
aborting, or at least take a "-f" flag, but I can live with it :-).
