[imp-dev] Key word with hyphen

["Crapo, Andrew (GE, Research)" <crapo@xxxxxx>]

Title: Key word with hyphen

I'm upgrading from a very old version of IMP (about the time you became an Eclipse incubator project) to the latest version. I can't seem to get a keyword with a hyphen to work--worked in old version.

In KWLexer.gi:

%Export
…
    toplevel
…
%End

%Terminals
    a    b    c    d    e    f    g    h    i    j    k    l    m
    n    o    p    q    r    s    t    u    v    w    x    y    z
    A    B    C    D    E    F    G    H    I    J    K    L    M
    N    O    P    Q    R    S    T    U    V    W    X    Y    Z
    Hyphen ::= '-'
%End

%Rules
    Keyword ::= …..

              | t o p Hyphen l e v e l   /.$setResult($_toplevel);./
              ….
%End

%Headers
    /.
        static {
            tokenKind['-'] = SADLKWLexersym.Char_Hyphen;  // Map the hyphen character
        }
    ./
%End

Result is a error at the hyphen:

I've also tried it with

             tokenKind['-'] = SADLKWLexersym.Char_Hyphen;

Which is what worked in the old version.
