Specify the ascii code as octal after a backslash.

In your example, 11011111 is decimal 223 or octal 337. Try a Postfix of=20
'\337'

As for your other questions:

It has, indeed :-)

I'm afraid there is none at the moment. To get just a list of all=20
possible entries, do a 'grep cfg_ widget_*.c'

An expression is, as the name implies, an expression :-)

you can specify a (static) string by enclsoing it inside singel quotes=20
(e.g. 'this is a string')

But you can use any (mathematical and string) expression you like, as in

2*3+4
or
strlen(cfg('Display'))
or
cpu('busy', 500)

all of the 'functions' have been registered as so called 'plugins'. I'm=20
afraid there is no up-to-date list of plugins and/or functions, too.

So the only possibility at the moment would be UTSL.

The current CVS code should be released as 0.10.0 in a few weeks, until=20
then there will be documentation.
