Sorry, add also - I'm wondering what error did you encounter with this way?

function Log_Error
lparameters toError
local lcError, lcVars

lcError = [Error: ] + transform(m.toError.errorno) + CRLF + ;
	[LineNo: ] + transform(m.toError.lineno) + CRLF +  ;
	[Message: ] + m.toError.message  + CRLF +  ;
	[Procedure: ] + m.toError.procedure + CRLF +  ;
	[Details: ] + m.toError.details  + CRLF + ;
	[StackLevel: ] + transform(m.toError.stacklevel) + ;
	iif(_vfp.startmode = 0, CRLF + [LineContents: ] + m.toError.linecontents, '')


return m.lcError
