$Lstr_Index

Find a string inside a longstring

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Lstr_Index function is are the PositionOf (String function) and the PositionIn (String function).

This function takes two longstring inputs and produces the position of one input inside the other.

The $Lstr_Index function accepts three arguments and returns a numeric result.

The first argument is an arbitrary longstring. This is a required argument.

The second argument is a longstring whose length, ironically, must be 255 bytes or less. This is a required argument.

The third argument is a number indicating the position within the first string that a search for a match is to being. This is an optional argument and defaults to 1 meaning the first character.

Syntax

%result = $Lstr_Index(longstring, str, start)

$Lstr_Index function

%result is the position in longstring of :hp1.str:ehp1., if there's a match after start, or is 0 if not.

$Lstr_Index acts very much like $INDEX except

It allows a start position other than 1 (argument 3).
It cancels the request if the string being searched for (argument 2) is longer than 255 bytes.
It can operate on LONGSTRING inputs.

For example

%X = $Lstr_Index('Beauxbatons', 'bat')

sets %X to 6 and

%X = $Lstr_Index('Dudley Dursley', 'ey', 8)

sets %X to 13.

$Lstr_Index is only available in Sirius Mods Version 6.2 and later.
