I have a problem when I program a method : I dont know how to use "sprint("buffer1",i)" ,here,the type of "i" is an integer.Even though I had searched from "context help" I still cannot find useful information. I hope you can teach me how to use "sprint("buffer1",i)" and explain the meanning of the "sprint("buffer1",i)",It's much better if you can give an example.
The sprint function is the same as the to_str function. sprint is just the old name.
All the function does is to convert all the arguments into a concatenated string. So if you execute to_str(2.3,", ", 4) you will get the string "2.3, 4".
Or in your case if let's say the variable i is 4 you will get the string "buffer14".
