We have, in fact, done so. But thanks for the advice all the same, we will
probably implement something like your suggestion in a following release :-)

Again, thanks very much for the advice, I have removed the xmc entry from
my terminfo source and all works great, except and wait for it, every time
I emit wattroff I get a '%' on the screen! Yes it does appear that the double
percentage in the rmacs and sgr0 sequences are _not_ required!

Sorry, it takes so long for me to respond. Lots of development pressures :-)

Another problem that we have for curses is that we can not place an alternate
character (not using ACS_ ) at the bottom right hand corner of the screen, This
is for all terminals we use ie. SCO ansi, freedom 100, vt100, vt220, qvt101.
