The right-most characters of the string (String class)
The Right intrinsic function returns the right-most characters of the method object string, possibly padding it on the left.
Syntax
%outString = string:Right( length, [Pad= c])
Syntax terms
| %outString | A variable to receive the string result of the Right method. |
|---|---|
| string | The input, method object, string to which the method is applied. |
| length | The number of the right-most bytes to return. If the method object string is shorter than the requested length, it is either padded to the requested length or the entire method object string is returned with no padding, depending on the value of the Pad parameter. |
| Pad | This is an optional, but nameRequired, parameter; used to pad the method object string, on the left, if it is shorter than the requested length. pad defaults to a single blank space. If set to the null string, no padding is applied. |
Usage notes
- The length must be a non-negative number. A negative number results in request cancellation.
- The pad parameter must be either null or a single character. A longer value results in request cancellation in "Sirius Mods" Version 7.2 and in a compilation error in "Sirius Mods" Version 7.3 and higher.
- Right can be useful for right-justifying a value in a string, most typically by using a blank space as pad character.
- Right is available as of "Sirius Mods" version 7.2.
Examples
- The following places the right-most 5 bytes of %x into %y. If %x is shorter than 6 bytes, then all of %x is copied into %y:
%y = %x:right(5)
The following request right-justifies the numbers 7, 123, and 99, and it left-justifies the number 88:
begin printText {7:right(5)} printText {123:right(5)} printText {99:right(5)} printText {88:right(5, pad=)} end
