Create new Stringlist instance (Stringlist class)
This method returns a new instance of a Stringlist.
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:
Syntax
%sl = [%(Stringlist):]New[( [imageName])]
Syntax terms
| %sl | A Stringlist object that is set to a new Stringlist object reference. |
|---|---|
| imagename | A 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.
- 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')For more information about the association or binding of an image to a Stringlist, see Bindiamge (Stringlist function).
