Shifting The Display On The Screen; Returning To Dos - IBM 5150 Manual To Operations

Shifting the Display on the Screen
You may find that the first two or three characters on a
line of the display do not show up on the screen. If your
display device does not have a horizontal adjustment
control, you can do this to shift the display, whether
Cassette BASIC, Disk BASIC, or Advanced BASIC is
running:
1
When you see BASIC's prompt, Ok, type this:
out 980,2: out 981,43
Check your typing, and correct if necessary. Then press
the Enter key.
Note: You can also shift the display from DOS.
See the section "MODE-Shifting the Display on the
Screen" in the "Using DOS" chapter.
For other information about Cassette BASIC, see the
BASIC book. The remainder of this section assumes
that you are using Disk BASIC or Advanced BASIC.
Returning to DOS
Sometimes you will want to return to DOS after running
a BASIC program. For example, you might want to use
COpy to make a back-up copy of a file that a BASIC
program created or to change from Disk BASIC to
Advanced BASIC.
To return to DOS from BASIC:
1
Make sure BASIC is ready for a command-Ok is
displayed.
2
Type this:
system
and press the Enter key.
3
Now you will see the DOS prompt, A>, and you can
give DOS a command.
