[SAC-HELP] summing 2 components in SAC...!!

[Talal Merghelani]

Hi
   
  first, i would like to deeply thanks all people helped me in the past and give their experince and notes about my questions.
   
  here, i would like to perform a vector summ of the 2 component EW and NS after FFT.
  for a set of files (say 90).
   
  in this form of formula: sqrt((EW)**2+(NS)**2)
   
  how do i do this operation in sac using a macro..? 
   
  for your note, the EW & NS component in the equation is a file name which is contain the spectral data for each components.
   
  how do i use the file name inside this forms using a macros for example to preform it for a set of files..?
   
  any idea..?
   
  i appreciate it..
   
  Talal
