Hi Rick,

>That does the trick. Thanks, George.

Glad to help.

>It's interesting that _WClear didn't work when some of the other API commands do. For example, the following works to select the contents of the debug output window

lnwhandle = _WFindTitl('Debug Output')
>= _EdSelect( lnwhandle, 0, 9999)

= _EdDelete( lnwhandle)

or

= _EdCut( lnwhandle)

doesn't throw an error but doesn't clear it either.

I think the reason that these functions don't work, is that they were designed for editing windows (prgs, hs, and txts). You can have some fun there. If I recall correctly, _WClear, etc. doesn't actually remove the text in these. It looks like it does, but actually just repaints the screen. What I find interesting is that _WFindTitl() works from the command window for the debugger, but not in a program.
