Create new Stringlist instance (Stringlist class)
This method returns a new instance of a Stringlist.
Syntax
%sl = [%(Stringlist):]New[( [imageName])]
Syntax terms
| %sl | A Stringlist object that is set to a new Stringlist object reference. |
|---|---|
| imageName | An, optional, string that contains the name of an image to be "associated" or "bound" to the sl Stringlist. This is an optional argument. This argument is case sensitive. That is, in the likely event the User Language was written in mixed case, with automatic upper-casing in effect, the image name should be in uppercase (see Mixed-case User Language). |
Usage notes
- All errors in New result in request cancellation.
- New is a constructor and as such can be called with no object, with an explicit class name, or with an object variable, even if that object is null:
%sl = new %sl = %(Stringlist):new %sl = %sl:new
- Specifying an image name on the New method is identical to using a simple New with no parameters followed by a BindImage method on the new object:
%list = new('IMAGENAME')
is equivalent to
%list = new %list:bindImage('IMAGENAME')
