open input file and new output file read a line of the input data and record the field name (id001 etc.) if the field name is new / has changed, output a newline (exept for the first line), the field name and the value. if it is not new / has not changed, output only the value. read next line from input file and repeat procedure close files joe -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
