INSERTING, ALTERING AND DELETING A WORD 

 
This section outlines the procedure for inserting, altering, and deleting 
a word in a program registered in memory. 

 

Procedure for inserting, altering and deleting a word 

 
1 

Select EDIT mode. 

2 

Press the function key 

. 

3 

Select a program to be edited. 

 

If a program to be edited is selected, perform the operation 4. 

 

If a program to be edited is not selected, search for the program 
number. 

4 

Move the cursor to the position to be edited, with one of the 
methods below. 

•

 Scan 

method 

•

 

Word search method 

•

 

Address search method 

For each method, refer to III-10.2.1. 

5 

Perform an operation such as altering, inserting, or deleting a 
word. 

 

Explanation 
  - Concept of word and editing unit 

A word is an address followed by a number.    With a custom macro, 
the concept of word is ambiguous. 
So the editing unit is considered here. 
The editing unit is a unit subject to alteration or deletion in one 
operation. In one scan operation, the cursor indicates the start of an 
editing unit. 
An insertion is made after an editing unit. 
Definition of editing unit   

•

 

Program portion from an address to immediately before the next 
address  

•

 

An address is an alphabet, IF, WHILE, GOTO, END, DO=, or ;   
(EOB). 

According to this definition, a word is an editing unit. 
The word "word," when used in the description of editing, means an 
editing unit according to the precise definition. 

 

 WARNING 

 

When a change, insertion, or deletion was performed on data of 
a program by pausing machining with the single block stop, feed 
hold, or other operations during execution of a program, be sure 
to return the cursor to the original position before restarting the 
program.    To execute the program with the cursor positioned at 
another position, be sure to make a reset. 

 

Otherwise, the program may not be executed as expected from 
the program shown on the screen after machining restarts.
