Introduction #

String in a programming language is a sequence of characters. It is used to represent text rather than numbers.
Strings are contained within a pair of double quotes, i.e. "Cat" or "Hello World".
Strings can contain numbers, however you must realize that "5" doesn’t have the value of 5, it has the value of 0, the same as "a" does.
You cannot add strings either, i.e. "12" + "34" isn’t "46", it’s "1234". 12 + 34 is 46.
If you wish to convert a string to a number, you can use String to Number command.

In SAMMI, use strings without double quotes in white input boxes, and enclose them in double quotes if the input box is yellow.Otherwise SAMMI will read them as real values and convert them to 0.

String Position #

String (text)	String	String to search inside of
String To Search For	String	Value to search for
Search From Position	number	What position in the string to start the search at, default is 0
Case Insensitive	Checkbox	If this is checked, it will return the first matching value, regardless of case.

Value to search for	String	From Location	Case Insensitive	Position returned
hello	hello and hello world	0	Unchecked	1
hello	Hello and hello world	0	Unchecked	11
hello	Hello and hello world	0	Checked	1
hello	Hello and Hello world	0	Unchecked	0
hello	Hello and Hello world	0	Checked	1
hello	hello and hello world	5	Unchecked	11 (finds the second `hello` since we’re searching from the 5th letter in the string)

String Clamp #

Hello World!	1	5	Hello
This is cool!	9	4	cool
