Hari,

I am not sure about what you are asking. Can you explain more fully?
>I know the interface
>face has so fixed value to look for the location. Can I modify my interface
>code to make it global search? where do I need to make changes? Some hint

Do you mean that you want to change your application to be able to
access data held on a remote machine that is running the remote ADDE
server? Please explain what your specific objectives are.

>>Hari,
>>
>> >Here is my code in fortran to take location.

>>

>>elements, change selects(1) to:
>>
>> selects(1)='SIZE 600 800'

>>After making the change, of course, you will need to rebuild your
