ISTR it was an issue back when jphoward wrote his BSD-licensed grep. However, it's not the same engine - it's Spencer's old engine with multibyte support added. IIRC, it performs very poorly compared to the GNU regexp engine; it would be interesting to see how well the Tcl engine performs in comparison. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
