Personally I like to break long complex commands up like the following, with the parameters on a seperate line. It makes it easy to comment them out, remove them or add new parameters. I also find it easier to read.

 Code:
Shell '"'+%COMSPEC%+'" /C'
	+' "'+%SYSTEMROOT%+'\microsoft.net\framework\v2.0.50727\caspol"'
	+' -machine'
	+' -addgroup LocalIntranet_Zone'
	+' -strong'
	+' -hex 002BFA80333BF  HostedWinFormsControls'
	+' -noversion ALPHAWeb'
	+' -description "Permissions for WinForms Controls hosted in the Alpha Web Application"'
	+' -name Intranet_PDSHostedWinFormsControls"
