Specify Filename In Save As Dialog Using Windowscommands.dll

[APTS 3]

It is almost 2016.  What is currently the best method for typing a text filename into a windows Save As dialog? Here is my current code:

     click(<pid=87>,"Left Click","No")
    wait(.5)
    change checkbox(<id="rsAddMap">,"Checked")
    click(<id="rsPhoto">,"Left Click","No")
    wait(.5)
    click(<id="rsViewReport">,"Left Click","No")
    wait for element(<id="download">,30,"Appear")
    wait(.5)
    set(#url,$replace($url,"#",""),"Global")
    set(#pt1,"www.targetsite.com","Global")
    set(#pt2,$scrape attribute(<tagname="iframe">,"src"),"Global")
    navigate("{#pt1}{#pt2}","Wait")
    wait for element(<id="download">,30,"Appear")
    wait(10)
    click(<id="download">,"Left Click","No")
    comment("What can I do here to interact with the Save As dialog?" )
    stop script

 

The above code takes me as far as opening the windows Save As dialog box and specify a default file name.  How do I specify my own filename and then click the enter button?
