I have this command:

window -Bk[0] @WebView $scriptdir\icos.icl 7

What would I put to change it's size (if you can show me, just do 1 height and 1 width and I can get it to the size I want).

/window -Bdk0 @WebView 100 100 790 546 $scriptdir\icos.icl 7

from helpfile
x,y,w,h left top width height

Note: If you specify -1 for any of the x,y,w,h values, a default value is used, unless the window exists in which case the current value is used.
