Entry and Revision of Task or Function Choices on a CRT

On cathode ray tube (CRT) systems that format task or function decision via choices (menus), entry of new menus and revision of old menus is a necessary and useful ability.

In general, the menu facility is used by an operator to invoke the task or function to be performed and to specify a set of associated parameters. Each menu contains an "ID" column and an "ITEM" column. The ID column contains a letter that is used by the operator in communicating to the CRT system which parameter, directive or multi-line option is to be entered or revised. The item column contains the name of the option by which the operator may identify a particular option. It is strictly an informational column.

Some menus contain only the above two columns. Others contain another column called "your choice" and a "possible choices" column. The "your choice" column lists the current value of the option identified by the ID and item column entries.

Menu options are selected by keying the "ID letter" of the option and pressing the enter key when the system displays the following on the prompt line: Type ID letter to choose ITEM press ENTER:

If the operator keys and enters an invalid ID (e.g., one not on the displayed menu), the system will continue to display the above prompt with a cursored space following the invalid keyed entry and will also display the following informational message on the message line: Invalid ID letter.

For editing parameter option lists, the system provides two methods: the leading prompt method and the short form method.

The leading prompt method uses prompts on the prompt line to direct or lead the operator through the steps necessary to edit a specific parameter. Initially, the prompt "Type ID letter to choose ITEM; press ENTER: " will appear on the prompt line prompting the operator how to select an item whose parameter is to be changed. Once this is done, the "ID" and "ITEM" fields of the selected parameter a...
