Set/Export Env Vars from with Shell Script With Input Variable

I have a shell script I want to run that will set environment variables based on the value of an input variable submitted when the shell script is called. For example:

$ mgenv.sh prod

This would set environment variables for prod

$ mgenv.sh test

This would set environment variables for test

When I run the script using the syntax above, it works fine. However, my environment variables are not being set. Example of the syntax used in the shell script:

FIN_INTERFACE_DIR=\u06\interfaces\$1;export FIN_INTERFACE_DIR

Like I said, the script runs to completion, no errors reported - and then I check my environment variables and FIN_INTERFACE_DIR is not set.

If I take the input variable of the equation and hard code in my environment variables like so:

FIN_INTERFACE_DIR=\u06\interfaces\prod;export FIN_INTERFACE_DIR

Then run it with this command:

$ mgenv.sh

I get the same result - the script runs through clean without errors but no environment variables are set.

HOWEVER, my next test was to use the hardcoded variable but run the script with the following command:

$ . ./mgenv.sh

This worked great! Environment variable was set and exported. Finally - I use the new command and re-institute the use of the run-time variable $1 and run the following command:

$ . ./mgenv.sh prod

At this, I get the dreaded

1: parameter not set

So - how can I run this script with an input parameter and have it actually set environment variable? Any suggestions? Thanks.

export

asadmin-export(1AS)						   User Commands					       asadmin-export(1AS)

NAME

       asadmin-export, export - marks a variable name for automatic export to the environment of subsequent commands in multimode

SYNOPSIS

       export  [ name=value  [ name=value]*]

       Marks  a variable name for automatic export to the environment of subsequent commands. All subsequent commands use the variable name values
       as specified; unless you unset them or exit multimode. If only the variable name is specified, the current value of that variable  name	is
       displayed.  If  the  export  command  is  used  without	any arguments, a list of all the exported variables and their values is displayed.
       Exported shell environment variables set prior to invoking the asadmin utility are imported automatically and  set  as  exported  variables
       within asadmin. Unexported environment variables cannot be read by the asadmin utility.

OPERANDS

       name=value	       variable name and value for automatic export to the environment to be used by subsequent commands.

       Example 1: Using export to list the environment variables

       asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
       asadmin> export AS_ADMIN_PREFIX=server1.jms-service
       asadmin> export //to list the environment variables that are set
       AS_ADMIN_HOST=bluestar
       AS_ADMIN_PORT=8000
       AS_ADMIN_USER=admin
       AS_ADMIN_PASSWORD=********
       AS_ADMIN_PREFIX=server1.jms-service

       Where:  the export command lists the environment variables that are set. In this case, the environment variables have been set to: the host
       is bluestar, the port is 8000, the administrator user is admin with an associated password, and the prefix is server1.jms-service.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
