Hi,
You'd have to tell us what the error is exactly. For example, the
following code seems analagous to what you've provided, but it works
fine:
c:/users/root> java jess.Main
Jess, the Java Expert System Shell
Copyright (C) 1998 E.J. Friedman Hill and the Sandia Corporation
Jess Version 5.0a5 5/27/99
Jess> (bind ?s (new java.lang.String "ABCDEFGHIJKLMNOPQRSTUVWXYZ"))
<External-Address:java.lang.String>
Jess> (deffunction builds (?n $?rodes)
(foreach ?x $?rodes
(bind ?code (call ?s indexOf ?x))))
TRUE
Jess> (builds 1 A B C)
2
Jess>
(The astute reader will notice that ?s is not a defglobal. In Jess50a5
you can bind ordinary local variables at the global scope. Makes
experimenting at the keyboard much easier!)
