4MELFA-BASIC V
(4) Specifying work coordinates by this command clears WO, WX and WY data for the corresponding work
coordinate number [coordinate values of 3 points to be taught as work coordinates - parameters:
WKnWO, WKnWX, WKnWY (n: 1~8)].
Example) Executing Step 4 (P_WKcORD(2)=PW) of Reference Program <1> which is previously listed
causes WK2WO, WK2WX and WK2WY to be set to "0".
(5) Only MELFA-BASIC V can be used.
(6) In the Ex-T control interpolation command, this variable is referred to by the designated work coordinate
number and used as the Ex-T control point. Therefore, specifying P_WkCord also specifies the control
point coordinates in the Ex-T control.

[Reference Program]
1 P1=P_Zero
[Explanation]
(1) This can be used to initialize the P variable to zeros.
(2) This variable only reads the data.
