Privet Edward.
Thanks for your reply.

FOR EXAMPLE...

FORM1.COMMAND.CLICK
line1. replace table.field1 with "1"
line2. it is line with error
line3. replace table.field2 WITH "2"

In the line 2 there is an error. The function the error handler "ONERROR" is called.

PROCEDURE ONERROR
LPARAM ....

FOR i=_screen.formcount to 1 step -1
....
_screen.forms(i).RELEASE
ENDFOR

After that we come back on line3 (REPLACE) of an example and we receive an error... (Show open table dialog window)
How to make so that a method did not proceed after _screen.forms(i).release ()
