Now type EDIT 100 and hit

[ENTER]

. The Computer will display:

100 _

You are now in the Edit Mode and may begin editing line 100.

NOTE:

EDITing a program line automatically clears all variable values and

eliminates pending FOR/NEXT and GOSUB operations. If BASIC encounters

a syntax error during program execution, it will automatically put you in the

EDIT mode. Before EDITing the line, you may want to examine current

variable values. In this case, you must type Q as your first EDIT command.

This will return you to the command mode, where you may examine variable

values. Any other EDIT command (typing E, pressing ENTER, etc.) will clear

out all variables.

ENTER key

Hitting

[ENTER]

while in the Edit Mode causes the Computer to record all

the changes you've made (if any) in the current line, and returns you to the

Command Mode.

Space-bar

In the Edit Mode, hitting the Space-bar moves the cursor over one space to

the right and displays any character stored in the preceding position. For

example, using line 100 entered above, put the Computer in the Edit Mode so

the Display shows:

100 _

Now hit the Space-Bar. The cursor will move over one space, and the first

character of the program line will be displayed. If this character was a blank,

then a blank will be displayed. Hit the SpaceBar until you reach the first

non-blank character:

100 F_

is displayed. To move over more than one space at a time, hit the desired

number of spaces first, and then hit the space-bar. For example, type 5 and

hit Space-bar, and the display will show something like this (may vary

depending on how many blanks you inserted in the line):

100 FOR I=_
