I have a perl program that changes certain values in an input deck and runs an executable, opens the output file, finds the important number and stores it in an array.

I have two questions:

• When I use the s/old_value/new_value/ command for the input deck, is there a way to force new_value to be of a certain format (ie %.5)?
• When I do fill the array output_values and want to print it, how do i use a variable number of format qualifiers in the print command: i.e. instead of

  printf PLOT ("%.5f %.5f %.5f \n", $a[1}, $a[2], $a[3]);
  [download]

  I would like to do this print statement for "m" values of the array $a without having m be predetermined.

I looked through the previous submissions, and I could not find a similar type question. I apologize if it has already been addressed.
