Why not just use subscripts?
ie...
#! /bin/ksh
PARM[0]=hello
PARM[1]=world
ZERO=0
ONE=1
echo ${PARM[$ZERO]}
echo ${PARM[$ONE]}

Sorry guys...perhaps I didn't explain it well enough. Let me try again...
If I have three parameters in a script thus:
PARM1=hello
PARM2=world
PARM3=bye
and I now build a for loop to echo the values
for i in 1 2 3
do
echo PARM$i (this is where I am stuck)
done
When I run the script I would want to see
hello
world
bye
instead of
PARM1
PARM2
PARM3
Hope that is clearer. I am stuck figuring out how to expand the PARM# into
the variable's actually value.
TIA

PARM10=hello

If I have the above in a script and I want to echo the value of my
parameter PARM10, how would I do that by combining my AZ parameter. For
instance I want to be able to do
echo $PARM$AZ
and have it echo the value of PARM10 to say hello. I can't figure how to
quote it to expand $PARM10.
TIA
