mid

 

 

Description

The mid function returns a specified number of characters from a Text or String argument, with a specified length and starting at a specified character.

When to use

The mid function is used to create a substring of a specified length {length} starting from a specified starting position {start}.

 

Syntax

(mid string start length)



Name Description AIS Types
string The Text or String containing the character(s) you want to extract. String or Text
startAny positive integer representing the position of the first character you want to extract from text. That is, to begin with the first character in the text, set start to zero, for the second character, set it equal to one and so on. If start is greater than the length of text, mid returns the empty string "". If start is less than the length of text, but exceeds the length of text, mid returns the characters from start to the end of the Text or String. If start is less than 0, mid returns an error code.Integer
length Specifies how many characters to return from Text. If length is negative, mid returns an error code. Integer


Returns:

The substring of length {length} starting from the middle character of the String or Text.

 

Examples

Here are a number of links to Lambda coding examples which contain this instruction in various use cases.

Example_String_mid_001

These examples return a substring of a specified length and with a given starting position in the source String or Text object.
