List Command timed_mark_abs
Function marking vector to the specified position in the image field using the specified duration
Parameters
xval,
yval
time
Integration Pascal:
C:
Basic:
• The parameter time will be rounded down to a multiple of 10 µs (within the allowed
Comments
range).
• A timed mark (jump) command will not be executed with the normal marking speed
(jump speed). Instead, the speed (i.e. the number of microsteps) will be adjusted
so that the vector lasts exactly as long as specified.

• Note: After a timed mark command, a mark delay or a polygon delay is inserted, just
like after a normal mark command. That means the total time for the command is the
specified time plus the mark delay or polygon delay.
• Subsequent
normal marking speed. (See

List Command timed_mark_rel
Function marking vector to the specified position in the image field using the specified duration
Parameters
dx, dy

Basic:
Comments • The coordinates are relative to the current position.
• The maximum value for the absolute coordinates is ±32767 bits.
