Need to simplify code list files in directory

I have the following code that print certain files in my directory and groups things together. I would be good to tidy and simplify this code up and would greatly appreciate suggestions.

if ($opt_raytrac == 1) then
  echo ""
  echo -n "\033[2;34m"
  echo "-- Browse files for raytrac program -------------------------------------------------------"
  echo -n "\033[m"
  echo ""
  echo "   Looking in directory $pth"
  echo ""

  echo -n "\033[2;34m"
  echo "-- Base files -----------------------------------------------------------------------------"
  echo -n "\033[m"
  echo ""

  set fileLst = `find $pth -maxdepth 1 -name "*.base" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`

  if (${%fileLst} > 0) then
    if ($opt_chkColPos == 1) then
      $path_tcsh/printTable.tcsh --check $fileLst
    else if ($opt_sortFlds == 1) then
      if ($opt_groupTbl == 1) then
          $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn --group=$groupPtn $fileLst
      else
          $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn $fileLst
      endif
    endif
  endif

  echo -n "\033[2;34m"
  echo "-- Sources files --------------------------------------------------------------------------"
  echo -n "\033[m"
  echo ""

  set fileLst = `find $pth -maxdepth 1 -name "*.sr" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`

I am thinking of a way forward and considering this proposal:

I create a series of list with the specific search criteria -

set fileLst1 = `find $pth -maxdepth 1 -name "*.base" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`

  set fileLst2 = `find $pth -maxdepth 1 -name "*.sr" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`

  set fileLst3 = `find $pth -maxdepth 1 -name "*.rc" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`

set fileLst4 = `find $pth -maxdepth 1 -name "*.cmd" ! -regex '.*/\..*' -type f -print  \
    | sed 's/^.*\///'`
... etc

Then I perform a foreach loop to process

  if (${%fileLst} > 0) then
    if ($opt_chkColPos == 1) then
      if ($vrbLevel > 1) then
        echo "\n   $path_tcsh/printTable.tcsh --chk-ColPos"
      endif
      $path_tcsh/printTable.tcsh --check $fileLst
    else if ($opt_sortFlds == 1) then
      if ($opt_groupTbl == 1) then
          if ($vrbLevel > 1) then
            echo "\n   $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn --group=$groupPtn"
          endif
          $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn --group=$groupPtn $fileLst
      else
          if (($opt_verbose == 1) && ($vrbLevel >= 3)) then
            echo "\n   $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn"
          endif
          $path_tcsh/printTable.tcsh --shift=3 --sort=$sortPtn $fileLst
      endif
    endif
  endif
