这种多层WHILE的 END_后面应该怎么转换
G0 G90 G54 X#8 Y#9
M3 S#21
G43 H#23 Z30. M08
G0 Z[#5+2]
WHILE[#5GT#6] DO1
G1 Z#5 F300
WHILE[#9LT#2/2] DO2
#9=#9+#10
G1 Y#9 F#22
X-#8
#9=#9+#10
Y#9
X#8
END2
#8=[#1+#3]/2+5
#9=-[#2+#3]/2+5
G0 Z[#5+2.]
G0 G90 X#8 Y#9
#5=#5-#7
END1
IF[#5LT#6]THEN #5=#6
G1 Z#5 F300
WHILE[#9LT#2/2]DO 3
#9=#9+#10
G1 Y#9 F#22
X-#8
#9=#9+#10
Y#9
