LNC MILLMACRO Program5.5.7 Instruction of VACANT Value1. All local variables of the specific level will be reset to VACANT when MACRO CALL.2. VACANT values will be ignored and not be interpreted when interpreting CNC commands.For example :When #1=10, #2=VACANTG00X#1Y#2; equivalent to G00X10;Hence, it is good for the compilation of MACRO content.3. Besides assign (=), the same as 0 when operatingFor example :For example:If #1=VACANT#2=#1, then #2=VACANTIf #2=#1+#1, then #2=04. Besides == !=, the same as 0 when using the conditioned statementsFor example :若 #1=VACANTIf #1=VACANT#1==#0 true#1==0 false#1 >= 0 true238 LNC Technology Co., Ltd.
