Radio Shack TRS-80 Model 100 Basic Manual page 76

Run the program. If you enter the name LINDA, the output will look like this:
i'M\ME? 1.... I NDf\
AGE I~"3 ~~
Ok
II
Obviously, the program is not working correctly. The correct age is 42, not 0. The
problem is in line 40. Variable A at the end of this line should be changed to AG.
Line 40 should appear as
£10 PRINT "AGE 15", AG
This error could be corrected by retyping the line as shown above. But instead, we'll
use the Editor to change the variable name to AG by inserting the single character G
after A. Type the command
ED I T (ENTER)
You will see the following displayed:
10 INPUT "NAME"; NS.

The Computer enters the editor mode and the program is displayed. The cursor is on
the first character of the program. The symbol
at the end of each line is used to display the carriage return character that is generated
when (ENTER) is pressed. The ..,.. displayed after line 60 is an end-or-file marker.
To insert the "G" after the variable A in line 40, the cursor must be moved so that it
is directly over the .... in line 40.
The cursor is moved using the four Cursor Movement Keys in the upper right comer
of the keyboard. The arrows indicate which way the cursor will be moved when the
key is pressed.
