Hi,

I would like to have != as an infix operator, but ...

    ECLiPSe Constraint Logic Programming System [kernel]

    Version 5.2 #10, Tue Jun 26 02:14 2001
    [eclipse 1]: op(10,xfx,'!=').

    Yes (0.00s cpu)
    [eclipse 2]: read(X),display(X),nl.
     a != b.
    syntax error: postfix/infix operator expected
    | a != b.
    |   ^ here

    No (0.00s cpu)

I do not want to quote the operator. Does anyone know how to do this? I 
guess the ! is being read as a cut?

Cheers,

Geoff
