Re: extract data and store

Hi !

I have only one more question before test the solution. If i have another file
type with the following structure :


   30 INC ANSW
   . . . . . . . . . CENTROB     . . . . . . . .          7
   1024 INC FAIL OWN
   . . . . . . . . . CENTROB     . . . . . . . .          0

etc.......

I need to extract some info from file to postgress, I supose is necesary to parse
file. What if the best form to do it ? Whit perl and pipe files ? or there are a
diferent form  ?

Thanks.
