pll libraries are used in order to share common code.

The COPY command in pll lib. is used to assign values between form items .

for eg.
if you want to assign item1 value to item2
you use
copy(:block.item1,:block.item2)

This has to be done this way as the items used in the form
are external entities to a library

I m select a block EMP with all item it is a database block,
===============================
-----if you want to assign item1 value to item2
you use
copy(:block.item1,:block.item2)---------
===============================

How i can use COPY procedure in this block EMP to assign value from itm1 to item2, when i click the execute_query button.
Or plz give me an example with steps how i will utilize this command.
Thanx

If you are not using any pll library then there is no need for copy command .You can directly assign 1 variable to another

Assuming you want to query on emp block you can go in the enter query mode enter the empno then click on the execute query button
