Ed's stuff does that. There's also an easy way with the scripting host:

lparameter pcProgram, pcArguments, pnShowWindow, plModal

local loShell, lnRetVal

loShell = createobject( "wscript.shell" )
lnRetVal = loShell.Run( pcProgram + " " + pcArguments, pnShowWindow, plModal )
return lnRetVal

>Found it tried it and it worked pretty fine. Thanks for that. Is it possible to have the program wait until the other app is completed before it continues.
