Right
See Also: String Functions, Left, Mid, Pos, Rtrim
Purpose
The Right function returns the right-most code points of a string up to a specified length.
Return Type
Syntax
(Right({string-value}, {length}))
Where:
- {string-value}: The string that characters will be extracted from.
- {length}: An integer value indicating the number of code points that are extracted from the right of {string-value}.
What It Does
The Right function returns the trailing (right-most) code points of {string-value} up to and including the character in position {length} as counted backwards from the end of the string.
String sName
Move "John Smith" to sName
Move (Right(sName, 5)) To Customer.LastName
In this example, the last 5 characters of the value in the variable sName ("Smith") would be moved to the database field Customer.LastName.
Sample
This sample separates a string into words by separating character groups (words) before and after any space in the text.
Function SplitStringIntoWords String sText returns String[]
String sWord
String[] Words
Integer iWordCount iSpacePos
// Repeat as long as sText contains data
While (sText <> "")
// Find the first/next space
Move (Pos(" ", sText)) To iSpacePos
// If a space was found
If (iSpacePos > 0) Begin
// Take the left part
Move (Left(sText, iSpacePos - 1)) To sWord
// Move the remainder to the text variable
Move (Right(sText, Length(sText) - iSpacePos)) To sText
End
// If no more spaces are found
Else Begin
// Make word equal to the text
Move sText To sWord
// Empty text to stop the loop
Move "" To sText
End
Move sWord to Words[iWordCount]
Increment iWordCount
Loop
Function_Return Words
End_Function
Procedure OnClick
String sText
String[] Words
Move "Split this text into words" To sText
Get SplitStringIntoWords sText to Words
End_Procedure
Notes
-
If the {length} parameter = 0, the
Rightfunction will return an empty string. If {length} is less than 0, the function will return the {string-value} parameter in its entirety. If {length} is greater than the number of characters in {string-value}, the function returns {string-value} in its entirety. -
If the {string-value} parameter is of a type other than string, its value will be converted to a string for output.
