writing into output file

Hi Raghu,

Reading through a file and based on a condition prepending a comment characters to the lines is fairly easy:
(let (from file)
   from = (infile "/tmp/test.il") ||
      (error "cannot open file...")
   (while (gets line from)
      (if <yourCondition>
         (println (strcat "# " line))
         (println line))))

I don't understand though what you want to do with the line number, can you please elaborate on this

Max

Hi Max,

I want to add prefix using line numbers.Is this possible ?

Your questions are very poorly formed, and so a lot of guesswork is involved as to what you're really asking. I'm really surprised you cannot work out the answers if they are as simple as we're guessing they are.

let((from to lineNum line)
  from=infile("input.txt")
  to=outfile("output.txt")
  lineNum=1
  ; no \n in the fprintf because gets leaves the \n in each line read
  while(gets(line from)
    if(lineNum>5  ; i.e. some condition
      fprintf(to "#%d %s" line)
    else
      fprintf(to "%s" line)
    )
  )
  close(from)
  close(to)
)

apologies Andrew.

I will avoid asking simple things

Thanks,
