Does anyone can help how to write vb script 
for this example: 
M2000 (that's my car 'z'i preparation start it works 
G91 X400 
M2001 
X300 
M2001 
X200 
M2001 
X300 
M2001 (You need to stop the program, to include (output1) 
It touches the limit switch (input1) then off (output1) then when you touch the microswitch (input2) again pkrene program while ignoring (input1) until the next cycle.) 
X690 
M2001 
M2002 (the script I returned the machine to the starting position and ready for a new cycle) 
This is a machine for automatic cutting of the rear dimension of krojnoj list which can be interesting and I reworked the screen for one axis with potreblim commands 
any help is welcome
