Deleting program blocks
You can delete any blocks in an existing program except the
BEGIN
and END blocks
To delete a block:
⇒
⇒ ⇒ ⇒ ⇒ Use the arrow keys to move to the block, or enter the block
number.
⇒ ⇒ ⇒ ⇒ ⇒ Press the DEL key.
When a block is deleted, the TNC automatically renumbers the re-
maining blocks. The block before the deleted block becomes the
current block.
It is also possible to delete an entire program section:
⇒
⇒ ⇒ ⇒ ⇒ Select the last block of the program section.
⇒ ⇒ ⇒ ⇒ ⇒ Press the DEL key repeatedly until all the blocks in the
section have been deleted.
