ID begins at 0001 and ends at 9999 and offset can be anything from +0.999mm to -0.999mm. The drilling program uses a CYCLE81 to drill to a nominal depth of 50mm, but I want to be able to read through each ID and apply the corresponding offset. So if my file looks like this: TITLE/INFORMATION ID,OFFSET 0001,0.100 0002,-0.200 0003,-0.500 0004,0.300 ... 5000,-0.200 then the output in the program would be the following depths: 1st hole = 50.100mm 2nd hole = 49.800mm 3rd hole = 49.500mm 4th hole = 50.300mm ... 5000th hole = 49.800mm The program runs to around 400 holes, so for the next program, the depths need to be read from 0401 (for example) onwards. I know I need to: 1. Ask the operator to input the ID for the first hole (e.g. 0401); (no idea how to prompt for this input) 2. Read the offset for that line; (using READ function) 3. Add it to the depth parameter for the CYCLE81 drilling depth; 4. Execute the drilling cycle; (using variable as part of CYCLE81 function?) 5. Read the next ID number; 6. Repeat from #2. What is the best way of doing this - can anyone show me an example? I have a little experience in using variables, but not in reading external files. Thanks in advance! Michael Morgan
