Routine Description:
|

|
|
Function called to display more information on the configuration

|
item and provide the user with the option to change the current

|
setting (if appropriate). If the User "OK's" out of the UI,

|
then the action code field in the DLL data block is set to the
|
|
appropriate (and configuration item-specific) action code so the
|
|
"Set" function can be called to perform the desired action. If

the user Cancels out of the UI, then the Action code field is
|
|
set to 0 (no action) and no action is performed.
