BASIC commands

3.2.43 CANCEL

/i
Type Axis command
Syntax CANCEL[(1)]
CA[(1)]
Description The CANCEL command cancels the current move on an axis. Speed-profiled
moves (FORWARD, REVERSE, MOVE, MOVEABS, MOVECIRC,
MHELICAL and MOVEMODIFY) will be decelerated at the deceleration rate
as set by the DECEL parameter and then stopped. Other moves will be imme-
diately stopped.
The CANCEL command cancels the contents of the current move buffer
(MTYPE). The command CANCEL(1) command cancels the contents of the
next move buffer (NTYPE) without affecting the current move in the MTYPE
buffer.
CANCEL works on the default basis axis (set with BASE) unless AXIS is used
to specify a temporary base axis.
Note:
• CANCEL cancels only the presently executing move. If further moves are
buffered they will then be loaded.
• During the deceleration of the current move additional CANCELs will be
ignored.
• CANCEL(1) cancels only the presently buffered move. Any moves stored
in the task buffers indicated by the PMOVE variable can be loaded into
the buffer as soon as the buffered move is cancelled.
Arguments N/A
Example FORWARD
WA(10000)
CANCEL
Example MOVE(1000)
MOVEABS(3000)
CANCEL ' Cancel the move to 3000 and move to 4000 instead.
MOVEABS(4000)
Note that the command MOVEMODIFY is a better solution for modifying end
points of moves in this case.

3.2.44 CHECKSUM

/i
Type System parameter (read-only)
Syntax CHECKSUM
Description The CHECKSUM parameter contains the checksum for the programs in RAM.
At start-up, the checksum is recalculated and compared with the previously
held value. If the checksum is incorrect the program will not run.
Arguments N/A
Example No example.

Type I/O command

Description The CHR command is used to send individual ASCII characters
which are referred to by number. PRINT CHR(x); is equivalent to
