Returns a portion, or substring, of a string.
The string from which you want to obtain a subset.
The number of characters into the input string at which this node begins its operation.
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
