here is the thing i am trying to do . I have a system variable called $OOCEA_INCOMING_READY, I want to be able to construct this variable name inside the script and use it. I am passing part of the variable name OOCEA as parameter but i am not able to use this variable after constructing the name , see below :
----------------- code a.sh ----------------------------------------------
#!/usr/bin/ksh
set -x
AGENCY=$1
AGENCY_CODE=$2
FILE_TYPE=$3
#
echo \$${AGENCY}_INCOMING_READY
ls \$${AGENCY}_INCOMING_READY
ls $OOCEA_INCOMING_READY
exit
-------------------------------------------------------------------------


./a.sh OOCEA 05 ITRN

+ AGENCY=OOCEA
+ AGENCY_CODE=05
+ FILE_TYPE=ITRN
+ echo $OOCEA_INCOMING_READY <<<< does not work
$OOCEA_INCOMING_READY
+ ls $OOCEA_INCOMING_READY <<<< does not work
$OOCEA_INCOMING_READY: No such file or directory
+ ls /u02/oocea/incoming/ready <<< this works if i hard code the
ITRN_20090430_0030.ZIP ITRN_20090430_1230.ZIP variable name .
+ exit

Have a look at the following code. It sets up a variable called FRED. It then holds that variable's name in another variable called VARIABLE. It then uses eval to get to the original variable which is what you need:

Code:

#!/bin/ksh

FRED="correct"
VARIABLE="FRED"
eval "echo \$${VARIABLE}"

exit

Try adding a backslash to the concatenated name:
$OOCEA\_INCOMING_READY
