Previous command and command in execution
(1) When the buffer is corrected following the operation mode change at single block stop, nothing will be displayed in
previous command and command in execution.
(2) When there is no block after sub program call or user macro call, a program error occurs at the last block of the des-
tination program. If a buffer correction is made in this state, the destination program will be displayed in the buffer
correction window, but the actual correction result will be reflected on the source program.
(3) The buffer cannot be corrected when the block where the buffer is corrected is in the forward side from the block called
at another nest level. The operation message "Buffer correct not possible" appears.
The buffer can be corrected when the block where the buffer is corrected is in the rear side from the block called at
another nest level.
(a) : The buffer can be corrected.
(b)(d) : The buffer can be corrected
because the block is in the
rear side from (a).
(c) : The buffer cannot be corrected
because the block is in the
forward side from (b).
