Use JavaScript to Call Local Programs With Commandline Switches

<A HREF="java script:;" TARGET="_self" ONCLICK=" ShellExJ('D:/Portable Programs/mIRC/Mirc.exe -portable')">mIRC</A>

is the line i want to use and itd be no problem if it werent for the -portable switch. how can i make it so its something like the regular target box in a normal shortcut.

normal shorcut format is like this:

"D:/Portable Programs/mIRC/Mirc.exe" -portable

if i add quotes and leave the -portable out then its invalid or something.

this is for purposes of an active desktop setup. not remote use only local. so theres no issue about calling to a local file.

also when loading the file i get a bunch of script errors but everything validates in dreamweaver so i dont know.
