Hello:
I've put this into a script:
 
 
A1=the
A2=one
A3=and
A4=only
 
SetVar()
{
for k in 1 2 3 4
do
echo $k|awk '{ printf("$A%s", $1) ; }'
done
}
 
theoneandonly()
{
echo theoneandonly
}
 
eval `SetVar`

 
 
Regards
 
Ignacio

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

Subject: Combining variables

PARM10=hello
AZ=10

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
