Where can I learn to work in Forms6i?

Hi all.
Maybe someone can help me? Where can I learn, work and develop in the forms?
Thank you.

Wow! He worked successfully!

Ok.

If it is not difficult for you, explain to me, please, on a sequence of performance.

I do not understand your question, what exactly do you want to know?

And I don't understand, it isn't: GLOBAL. AUTOQUERY do?

Usually a Forms application consists not only of a WBF, but a lot of different FMAS. Inside a fmb, you can only access the objects inside the fmb, so every WBF is a 'closed unit '. But you still have the need to interact between different FMAS. A part, call one fmb of another. You can use CALL_FORM or OPEN_FORM (or not so often used, NEW_FORM). But you want to not only start an another fmb, but also give a few a fmb contect to another (e.g. the department_id). This is where global variables implemented.
In the forms, you can set global variables simply in a value assigned to them. There is no need of some sort of definition or the declaration. The variable begins to exist when you first assign a value. This can be done in two ways:

-- assign 'MYVALUE' to the global VARNAME
:GLOBAL.VARNAME:='MYVALUE';

Or

-- if global VARNAME exists, do nothing,else create it and assign 'MYVALUE' to it
DEFAULT_VALUE('MYVALUE', 'GLOBAL.VARNAME');

using ERASE('GLOABL.) VARNAME"); you have once again, the variable.

I used: GLOBAL. AUTOQUERY just to set a flag, there is a current automatic request (I check the value of: OVERALL.) AUTOQUERY in PRE-QUERY-relaxation)
When you try your form, you will see that when you press your button, your query will be limited to the TXTDEPTNO value, you entered in your query block, but if you click in your datablock and run a query "manually" using the menu or Ctrl F11 you will get all the records of all of Deptno. It's a common technique if you want to give a context to another form, but allowing the user also query different data later.

In the second step, how we can narrow down a selection of data. Instead of all the columns to extraction only two or three, for example?

If you don't want all of the columns in a table in the form, simply delete the associated items.

I hope this helps.
