Editing a C program
Once in the editor, there are two modes for editing: the INSERT mode and the
OVERWRITE mode. Switch between these two modes by pressing the INS key.
The INSERT mode is automatically specified when you enter the editor. The insert
mode is indicated by a cursor thet looks like "_". While the computer is in the INSERT
mode, any characters that you enter from the keyboard are inserted between any
characters already on the display.
You can specify the OVERWRITE mode by pressing the INS key. The OVERWRITE
mode is indicated by a cursor that looks like "_". While the computer is in the
OVERWRITE mode, any character that you enter from the keyboard replace any
characters already at the current cursor position.
Search function
The editor search function lets you search through programs for specific character
strings. We will demonstrate the search function using the following display.
EDIT. .
SRCH .P. .R.
. .
The specified character string is located and displayed, with the cursor located at the
first letter of the string.
The number in the lower right of the display indicates the program line number.
You can search for the next occurrence of the string without entering it again with the
Shift NEXT function (written for once under the CALC key).
Jumping to a specific line
The editor allows you to jump directly to a certain line using the Shift LINE function
and entering the line number:
Shift LINE 3

printf("HELLO¥n");↵
