Hi all, Pretty self explanatory really. Can this code be made to run faster? Notes I have built it to an exe. I have put the exe in the same directory as the input and output files. While 1 $line = FileReadLine($hFile) if @error = -1 then ExitLoop for $i = 1 to 16 step 3 $iNum = StringMid($line,$i,2) $oHex = Hex($iNum, 8) FileWrite($OutputFile, $oHex) next FileWrite ($OutputFile, @LF) WEnd
