Pass Parameters between two forms

[Cobol]

My situation:
1. During filling out a form, a drop-down list box will populate some data.
2. Select a specific record from the drop-down list box.
So far, it's esay.

3. After selecting the record, click on a button and send the value to
another form and open it in order to run a query.
This is tough.

The point is how I can send the value to the query field of the will be
opened form.

Is there any particular reason why you want to use two different forms?
Passing parameters between forms is not as straightforward as it seems. It is
much easier to use two views instead of two forms, and then switch between
the views.
