Syntax

string2 = Strings.substring(string, startIndex, endIndex);

Description

This function returns the substring from position startIndex up to and including position endIndex of "string" . The substring computation has the following properties:

• If the startIndex is non-positive, it is set to 1 and a warning is raised.
• If the startIndex exceeds the string length, the returned substring is empty.
• If the endIndex is negative, it is set to the startIndex and a warning is raised. The returned substring is the single character at position startIndex of string.
• If the endIndex is non-negative and less than the startIndex, the returned substring is empty.
• If the endIndex exceeds the string length, it is set to the string length.
• It is only intended for ASCII encoded strings. For UTF-8 encoded strings the index is seen as bytes, and some index values may break the string inside glyphs or even inside code points.

Example

string1 := "This is line 111";
string2 := Strings.substring(string1,9,12); // string2 = "line"
string3 := Strings.substring(string1,9,0); // string3 = ""
