Also, I assume you want the counter (i) to be 1 the first time it is used?
If so you can do the following:

Code:

#Set initial value to 1
i=1

while read -r  myxcoord myycoord
do
    <do some stuff>
    ./dc_2002 && ./st_vac
    cp motion.out "$i$stn$mt"
    cp time.out "$((i++))$stn$vel"
    <do more stuff>
done

Notice only the second copy needs to increment the counter.

And crts is correct that there should be no spaces in seds

Hi Grail
I actually use a very similar one

)

Code:

#!/bin/bash
stn="edrz"
mt="mt"
vel="vel"
i=0
d=5
rr=30
while read -r  myxcoord myycoord
do
echo $myxcoord 
echo $myycoord
echo $i
sed  -i.bak  "s/Xs=[^,]*/Xs=${myxcoord}/" dc.in
sed  -i.bak  "s/Ys=[^,]*/Ys=${myycoord}/" dc.in

./dc_2002 && ./st_vac
echo $((i++))
cp motion.out "$i$stn$d$mt$rr"
cp time.out "$i$stn$d$vel$rr"
rm motion.out
rm time.out
done  < <( paste  coordinatex.txt coordinatey.txt)
