Treat a string as longstring
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $Lstr function.
This function takes a String or Longstring input and produces a Longstring output.
Syntax
%longstr = $Lstr(longstring)
%longstr is a copy of longstring.
The longstring argument is an arbitrary string or longstring.
Usage notes
- The main utility of the $Lstr function is to force a STRING WITH expression that is its argument to be upgraded to a LONGSTRING WITH expression.
Example
For example,
IF %COMEDIANS EQ (%WHO WITH ' Costello')
truncates %WHO WITH 'Costello' at 255 bytes before the comparison, even if %COMEDIANS is a LONGSTRING %variable.
However, this statement does not:
IF %COMEDIANS EQ $Lstr(%WHO WITH ' Costello')
