Re: Amazing....!!!

Hello everybody,

     As earlier said by some one you cannot access a database field 
variable in the program unless and untill U refer it by a program 
field. If, for what U thought was possible then just try out and see 
the value of  any other database variables which are not referenced 
in the program, I'm sure that U will not be able to get it.

That's all,
Have a nice day...
