Copy

Hi
Why we use .pll libraries in form and is the purpose of COPY command in libraies ?
Jani

pll libraries are used in order to share common code.

Plz send me a link or URL where i search in detail and learn how we share the code and use copy command and its parameters.

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
