Substring Operator

The Substring operator. Takes one string and two integer parameters.

What	Type
Syntax	Substring(s, offset, length)
s	string
offset	int
length	int
Return type	string

The Substring operator follows these rules:

• If the offset is larger than the string length, the operator returns ""
• If the length is larger than the string length minus the offset, the operator returns the entire string from the offset on (but does not pad!)
• If the length is negative, the entire string from offset on is returned.

Examples:

Expression	Result
Substring("Hello, World!", 0, 5)	"Hello"
Substring("Hello, World!", 7, 100)	"World!"
Substring("Hello, World!", 20, 10)	""
Substring("Hello, World!", 7, -1)	"World!"
