$Lstr_Left

<section begin="desc" />Leftmost characters of a longstring<section end="desc" />

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Lstr_Left function is the Left (String function).

This function takes a string or longstring input and produces the leftmost characters of the input, possibly padded to an indicated length.

The $Lstr_Left function accepts three arguments and returns a string result.

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

The second argument is a number between 1 and 2**31-1 that indicates the result length. This is a required argument.

The third argument is a string containing a single character to be used as the pad character if the result length is longer than the string specified by argument one. This is an optional argument and defaults to a blank.

Syntax

<section begin="syntax" /> %RESULT = $Lstr_Left(longstring, len, pad) <section end="syntax" />

$Lstr_Left function

%RESULT is the leftmost characters of the input longstring, padded with the pad character if necessary.

$Lstr_Left acts very much like $PADR except

The target length and pad character arguments are reversed.
It cancels the request if the result target is too short to hold the result.
It cancels the request if the pad character argument is longer than one byte.
It can operate on LONGSTRING inputs.
It produces a LONGSTRING output.

For example

%BIG = $Lstr_Left('Voldemort', 3)

sets %BIG to "Vol". and

%BIG = $Lstr_Left('Snape', 300, '!')

sets %BIG to "Snape" followed by 295 exclamation marks.

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