function ExtractLine( cText, nFrom )

I found out that if I use instead of
nAt := At( CRLF, SubStr( cText, nFrom ) )

nAt := At( CRLF, cText, nFrom )

the speed of the function is much better. Is it save to remove SubStr here?

Thanks in advance

function ExtractLine( cText, nFrom )
local cLine, nAt

nAt := At( CRLF, SubStr( cText, nFrom ) )

if nAt > 0
cLine := Substr( cText, nFrom, nAt - 1 )
nFrom += nAt + 1
else
cLine := Substr( cText, nFrom )
nFrom := Len( cText ) + 1
endif

return cLine

Yes in xHarbour.
