4.13 Adding Comments to the Program
You can add comments to the part program in the PROGRAMMING AND

Applications:
• To explain steps of the program
• To make general notes
Adding comments to program blocks
You can add comments to a program block immedi-
ately after entering the data by pressing the
semicolon key ";" on the alphabetic keyboard.
Pressing the key brings the dialog prompt:
C O M M E N T ?
Input:
• Enter your comment and conclude the block by
pressing the END key.
• If you decide not to comment after all, press the
END or NO ENT key: this will conclude the block
with the entered NC data.
If you wish to add a comment to a block that has
already been entered, select the block and press a
horizontal arrow key until the semicolon and the
dialog prompt appear.
To enter a comment as a separate block:
Start a new block by pressing the semicolon key.
Enter your comment on the alphanumeric keyboard.
Close the block.
Comments are added behind the entered blocks.

90 L X+10 Y+0 RL F100 the block.
