Insufficient information.
Sorry to say that but can you please bit more clear on your problem? That Variable is global? do you want local? and what actual problem you are facing?

define a global variable once you start your application

:global.curr_user := "aaa";
:global.form1_user := null;

and then when you start the form make a trigger on the form level

[ when new form instance ]

if :global.form1_user is null then
:global.form1_user := :global.curr_user ;
else
message('this form already in use by another user');
end if;

hi akramrabaya,

are you sure this method will work ?

i think we cannot share data between two instances of a forms application using global variables.

if i correctly understand your requirments that will work and already tested .....!!!!

i don't know what you mean by " share data between two instances of a forms application "

it is just a parameter can move between forms until you go out completely from the application session
