SUMMARY
Because msmail() is a HyperTalk function, it always returns a value.
This holds true even in cases when the effect of the msmail()
function, rather than the result it returns, is the purpose of the
msmail() call. For instance, when using the sendMessage call, the
value the msmail() function returns is unimportant; what is important
is the effect: mail is sent over the network to the server.
In cases like these, the result of the msmail() function must be
redirected; otherwise, HyperCard will put the result into the message
box. To keep the message box from appearing, use the HyperCard "get"
command, which will absorb the result of the function by putting it
into the HyperCard global "it". For example:
get msmail (sendMessage, myMessage)
