checkbox for omit records

Hello

I would like to have a checkbox - either a single box where a value entered ie Y which does the same as the omit records box on the status panel

So if the box checked and constrain found set is used then it will omit the found records

I should say that my layout is a custom layout where all the finding is done using buttons with scripts

Also is it possible to change the omit state using a variable ie Request the omit state using the function (normally would be 0) and then changing it to 1 by changing the value of the variable later in the script

Any pointers greatfully rec'd for this one
