Interactive Editing of Tables

An interactive editing facility EDIT/TABLE exists in MIDAS to create and modify tables. The editor works in a ``page-oriented'' form, a ``page'' consisting of 20 rows and several columns to fill the screen format, using a Keypad mode or a command mode to perform the editing functions. The command mode is accessible by hitting CNTL-Z. Most of the editing functions are implemented on the right keypad of the keyboard (Table 5.2) as well as on the left keypad if it exists (e.g on Sun workstations). Some keys of the central keyboard are also recognized (Table 5.7 ). The functions only available in command mode are listed in Table  5.6
