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

print(1)							   User Commands							  print(1)

NAME

       print - shell built-in function to output characters to the screen or window

SYNOPSIS

   ksh
       print [ -Rnprsu [n]] [arg...]

DESCRIPTION

   ksh
       The shell output mechanism. With no flags or with flag - or -, the arguments are printed on standard output as described by echo(1).

OPTIONS

       The following options are supported:

       -n	       suppresses new-line from being added to the output.

       -R

       -r	       (raw  mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
		       -n.

       -p	       causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.

       -s	       causes the arguments to be written onto the history file instead of standard output.

       -u [ n ]        flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.

EXIT STATUS

       The following exit values are returned:

       0	Successful operation.

       >0	Output file is not open for writing.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
