$Lstr_Unblank

Remove extraneous blanks from longstring

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

This function takes a string or longstring input and produces the a copy with leading trailing and duplicate internal blanks (or other pad character) removed.

The $Lstr_Unblank function accepts two 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 string containing a single character that is treated as the blank character. This is an optional argument and defaults to a blank.

Syntax

<section begin="syntax" /> %RESULT = $Lstr_Unblank(longstring, char) <section end="syntax" />

$Lstr_Unblank function

%RESULT is a copy of longstring with leading, trailing, and extra intermediate blank characters removed.

$Lstr_Unblank acts very much like $UnBlank except

• A character other than blank can be specified as the separator character (argument 2).
• It cancels the request if the result target is too short to hold the result.
• It can operate on a LONGSTRING input.
• It produces a LONGSTRING output.

For example

%BIG = $Lstr_Unblank(' Rubeus Hagrid ')

sets %BIG to "Rubeus Hagrid" and

%BIG = $Lstr_Unblank('!!Avada!!!!Kedavra!', '!')

sets %BIG to "Avada!Kedavra".
