2.1-28 Stacked Entries

Users should be allowed to key a sequence of commands or option codes as a single 'stacked' entry.

Additional Information:
In particular, users should be allowed to enter stacked entries from any menu so that an experienced user can make any specific entry without having to view subsequent menus. Entry stacking may be helpful when a user is being prompted to enter a series of parameter values, and knows what several succeeding prompts will request and what values to enter. Entry stacking will permit a transition from simple step-by-step entry by novice users, as in menu selection and question-and-answer dialogues, to the entry of extended command-language statements by experienced users. Entry stacking is especially helpful in time-shared systems where computer response to any user entry may be slow.
