Treat a string as longstring

Note: Many $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')
