>Yes, it works just fine. However, I don't know too many people who work with 6M strings in memory... a little clumsy.

lcTestString = replicate("ABCDEF",100000)
? LEN(lcTestString), SECONDS(), IIF(LEN(strtran( lcTestString, "BDF", "" ))>0, SECONDS(), 0)
lcTestString = replicate("ABCDEF",100000)
? LEN(lcTestString), SECONDS(), IIF(LEN(Chrtran( lcTestString, "BDF", "" ))>0, SECONDS(), 0)

just to give you an idea and a coffee break <g>. For lunch up the ante.
