Do u know these switches?

[Gord]

I have a user button that pops up MS Outlook with an
attachment. I need to know the switches that would allow
me to populate the email address, subject line and to put
some text into the email. Does anyone know these switches?
ie. // Runs MS Outlook with an attached file.
ls_run_string = '"' + ls_outlook + '" /c IPM.Note /m '
+ ' /a' + ls_attach
run(ls_run_string)
