Although this was posted in the PIC BASIC forum, you are probably using PicBasic Pro.
If using PBC that line would have given an Invalid Symbol error. PBC doesn't allow the @ symbol.

I would guess that you have the wrong chip selected in the Device drop-down in MicroCode Studio.

If you don't see a Device drop-down in the toolbar, go to View > Toolbars and make sure Compile and Program is checked.

hth,
