For loop

Hi all,
I have been trying to do something like below...but any idea how can I effectively make the for loop....


Code:
set tmp = 2
while ( $tmp <= 50 )
if ( $tmp == "1" ) then
set park = `echo "0"`
if ( $tmp == "2" ) then
set park = `echo "$park1"|bc`
else if ( $tmp == "3" ) then
set park = `echo "$park1+$park2"|bc`
else if ( $tmp == "50" ) then
set park = `echo "$park1+$park2+.......+$park49"|bc`
endif
endif.......endif

Many thanks

Something like this?
Code:
#!/bin/bash

park1=111
park2=222
park3=333
park4=444

tmp=2
while [ $tmp -le 50 ]
do
  park=0
  for((i=0;i<$tmp;i++))
  do
    val=$( eval echo \$park$i )
    ((park+=val))
  done
  echo $park
  ((tmp++))
done

I am not so good with csh/tcsh, try this...

Code:
#!/usr/local/bin/tcsh

set park0=0
set park1=111
set park2=222
set park3=333
set park4=444

set tmp=0
set val=0
while ( $tmp <= 5 )

  set park=0
  set i=0
  while ( $i < $tmp )
    @ val=`eval echo \$park$i`
    @ park = $park + $val
    @ i++
  end
  @ tmp++
  echo $park

end
