Maybe I'm wrong, but is this will accurate if the value "|" (0x7C or 124 decimal) appear in .DBF header?

I think this code below will prevent that case
lcData=FILETOSTR("timep.dbf")

*!* skip until first record
lnFirstRecordOffset = CTOBIN(SUBSTR(m.lcData, 9, 2), "2RS")

lnCount=OCCURS("|", SUBSTR(m.lcData, m.lnFirstRecordOffset + 1))
