Charley Chen

Hi All,

 I read a file which has 1386213 line  or more , only read each line  , it spend  7 minutes  and above.

How can it speed up ?

 

procedure( QQ(file)
   prog( ()
      inPort=infile(file)
           while( gets(inLine inPort)

               ........
           ) ;if
      ) ;while
       inPort=nil
  ) ;prog
) ;procedure

 

Thank you,

Charley
