Help Passing An Oracle parameter to a unix shell.

I have an Oracle concurrent program that I'm passing a parameter to a unix shell script. An example value of the Oracle parameter is PO_TOP. The Oracle parameter represents the unix env var PO_TOP, meaning, on the unix side there is env var called PO_TOP (ex value: /oradev/apps/po/11.0.3/). My goal is to passed the Oracle parameter to the unix script and have it behave like the unix env var $PO_TOP.

Example of the code in the script.
ora_base_dir=$1
echo "ora_base_dir: "$ora_base_dir
cd $ora_base_dir

--
This fails with a directory does not exist
the echo displays "ora_base_dir: PO_TOP"

Here is some examples of the not so brilliant stuff that I have tried:
ora_base_dir=$$1
ora_base_dir=$\$1
ora_base_dir=${$1}

All failed.

Can you pass the name of a unix env variable to a unix shell script and then set a new unix var to the passed variable?

Note: I'm trying to avoid using
IF $1= 'PO_TOP' THEN
ora_base_dir=$PO_TOP
ELSIF $1 = 'FND_TOP' THEN
ora_base_dir=$FND_TOP.....etc

There are over 200 unix TOP variables.

OCI_SET_CLIENT_INFO(3)													    OCI_SET_CLIENT_INFO(3)

oci_set_client_info - Sets the client information

SYNOPSIS
bool oci_set_client_info (resource $connection, string $client_info) DESCRIPTION
Sets the client information for Oracle tracing. The client information is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed. The client information can subsequently be queried from database administration views such as V$SESSION. The value may be retained across persistent connections. PARAMETERS
o $connection -An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3). o $client_info - User chosen string up to 64 bytes long. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Setting the client information <?php $c = oci_connect('hr', 'welcome', 'localhost/XE'); // Record the client information oci_set_client_info($c, 'My Application Version 2'); // Code that causes a roundtrip, for example a query: $s = oci_parse($c, 'select * from dual'); oci_execute($s); oci_fetch_all($s, $res); sleep(30); ?> // While the script is running, the administrator can see the client // information: sqlplus system/welcome SQL> select client_info from v$session; NOTES
Note Oracle version requirement This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards. Tip Performance With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack- age. This is less efficient than using oci_set_client_info(3). Caution Roundtrip Gotcha Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is enabled. SEE ALSO
