Hammer & Screwdriver Tweaking.

Well rested eyes are helpful. Key is to see that sequencing all the A,B,C,Ds is easier way to tackle.

This looks pretty good from the echo:

Code:
#!/usr/bin/ksh
for mInstance in $(echo "A B C D"); do
  for mServer in $(echo "1 2 3 4 5 6 7 8"); do
    echo "excute.lng Slave0$mServer Target0$mServer-$mInstance"
  done
done

OUTPUT:
excute.lng Slave01 Target01-A
excute.lng Slave02 Target02-A
...
excute.lng Slave07 Target07-D
excute.lng Slave08 Target08-D


Now let's see if I can change that to be a real cmd line arg and hope it runs ....

The solution is almost exactly as you described:
Code:
#!/usr/bin/ksh
for mInstance in $(echo "A B C D"); do
  for mServer in $(echo "1 2 3 4 5 6 7 8"); do
    echo "mInstance <$mInstance> mServer <$mServer>"
  done
done
