EDGAR allows the user to view and edit mUltiple portions of a given file. on
one screen simultaneously.
Figure 4 shows a sample screen layout with two "logical displays". Note the
second command line (Fig. 4, Line 11). Any Type I or II command may be
entered on either command line. Line 12 in Fig. 4 is the first data-display
area for the second logical display. This line is the "current line" for the
second logical display as indicated by the' /' at the start of the Type III
command area for this line.
The screen format of Figure 4 would result from the command: FORMAT 1-8 1-13 (see command discussion in Section IV).

Figure S. Sample screen with two logical screens.
A second form of screen subdivision permits the user to format a screen into
multiple logical screens by use of the SCREEN command (see Section IV).
Figure 5 shows a sample screen layout with two logical screens. Note the
second file status area (Fig. 5, Line 13). The significant feature of this
arrangement is that two or more different files can be edited and viewed at
the same time. When two or more logical screens are defined, EDGAR uses
them when possible in response to the ENTER command.
The screen format of Figure 5 would result from the command: SCREEN 12 12
