User LDA

Description
Sometimes you may wish to have the convenience of using a cut-down version of the DDM, but without the extra effort of creating a fresh LDA. This function allows you to suppress DDM fields on-the-fly.
To suppress DDM fields you give the command 'LDA'. PEEK will display the above screen which contains all of the DDM fields. From this list you select the fields which you wish to include in your user-LDA. Once the fields have been selected, the browsing screen is redisplayed, with only the selected fields visible.
You can toggle between the user-LDA and the DDM by using the command 'S' from either browsing screen in the same way as you would with a real LDA.
Whenever you are viewing either browsing screen and you wish to alter the field list, or cancel the current user-LDA, give the 'LDA' command once more.
