Eddie, your second example is something I have been using for quite a while.
Some (most?) format codes are not allowed to appear twice. Some are, but syntactically, they must differ (%sc comes to mind). Some require additional information in the same line (syntax rules for menu items). Others have loose rules; for example, you can have two menu items that refer to the same shortcut key sequence, but no error generated.
It would make some sense that a %ww with it numerous arguments could be split across multiple lines. Your first example is NOT what I was looking for. The syntax would be more like:
i = winio@('%ww[independent]&')
.
.
.
.
i = winio@('%ww[topmost]&')
Granted, in this simple example, it would make more sense to have it all in one line. Just imagine for a moment that the first statement is in a routine that creates a preamble to a window (with standard menu items, accelerator keys, %sc callbacks, etc.) and the second line is in the routine that requires this window have topmost status. Rather than complicating the situation with mostly unused arguments in the preamble call, just place the specific calls needed in the original module.
A bit different that your example.
