Returns a portion, or substring, of a string.
The string from which you want to obtain a subset.
The number of characters you want to include in the substring.
If length is negative or 0, this node returns an empty string.
Default: The entire length of string minus offset.
The portion of the input string that is the specified length beginning at the offset.
Characters in UTF-8 can be multiple bytes so string nodes count the number of characters in a string instead of jumping to a point in memory. Since the length and offset parameters are in units of characters, avoid nesting this node with large strings because that can create exponential functions that carry a higher performance burden.
Where This Node Can Run:
Desktop OS: Windows
FPGA: All devices (only within an optimized FPGA VI)
Web Server: Supported in VIs that run in a web application
