separator.

Axes for which nothing is specified keep their present location and do not

operate.

Example: When the present locations (for X, Y, Z, and A) are respectively

at  the  (100,  200,  300,  45)  coordinates  and  !ZE  X123Y456:X987Z-200

[terminator] is given, the X and Y axes first move simultaneously to (123,

456). At this time the other axes for

which nothing was specified (the Z and A axes) remain stopped. Next, the

X  and  Z  axes  move  simultaneously  to  the  coordinates  (987,  -200).

Similarly,  the  axes  for  which  nothing  was  specified  (the Y  and  A  axes)

remain stopped.

Giving  only  separators  without  stating  any  parameters  at  all  does  not

generate an error, but no operation is performed.

Example: !ZE:: [terminator]

Specifying  an  axis  that  the  model  used  does  not  have  causes  the

specification for that axis to be ignored, but the other axes operate.

When "!ZE X100Y200Z300 [terminator]" is specified for a model that has

no Y axis, the  parameter for Y-axis movement  is ignored, but the  other

axes (X and Z) move to their respectively specified locations.

Movement  operation  occurs  only  after  interpretation  of  the  separator  or

terminator.

When !ZE X100Y200:Z300A400; is given, the X and Y axes respectively

move to (100, 200) when the first separator is interpreted.

Next, the Z and A axis respectively move to (300, 400) when the final 

terminator is interpreted.

If  an  error  occurs  in  a  parameter  statement,  operation  including  the

parameter where the error occurred and everything thereafter up to the

terminator is skipped as invalid data.

When !ZE  X100Y200:Z300A:X0Y0Z0  [terminator]  is  given,  firstly,  the  X

and Y axes respectively move to (100, 200) at the first separator.

Then, because the next set of parameters contains an "A" parameter with

no specified numerical value, error 3 occurs at this point, and everything

up to the final terminator is skipped.
