g code: if then statement

[ebarrera]

I would like to create (2) if then statements that tells my machine to consider the current x position and then move in the y axis
I'm not sure if i am calling the current x position correctly because I believe only numbers can be within the "[ ]"

;if the current x position (absolute coordinate) is greater than or equal to 40,000 then the Y axis needs an offset of 2 mm
{if [G0 X] >= 40000} G1 Y2.00

;if the current x position (absolute coordinate) is less than to 40,000 then the Y axis needs an offset of -2 mm
{if [G0 X] < 40000} G1 Y-2.00

if this is a fanuc try
IF[#5041GE40000]THEN#100=2.0
IF[#5041LT40000]THEN#100=-2.0

#5041 Is current x position in the work co-ordinate system
#5021 is current x position in the machine co-ordinate system
Then you can use the #100 like this G1Y#100
