SUMMARY
=======

To add the data pointed to by a Macintosh handle to a mail message, use the
following syntax:

  msmail (addHandle, messageRef, handle, ident [, onlyOne] [, type])

This routine is similar to addField, except that instead of including the data
itself in the message, it includes the data pointed to by a handle. Together
with getMacResource, this call makes it possible to send resources through
Microsoft Mail.

"messageRef" is a reference to a selected message returned by making a call to
the msmail function using a parameter that returns a message reference.

"handle" is a Macintosh handle to a resource. This value is returned by a call to
getMacResource.

"ident" is a 4-character type identification for that handle, such as "ICON",
"CODE", "snd ", etc. These are Macintosh resource types.

"onlyOne" is a Boolean (true or false) parameter that can be passed to limit the
number of fields with the given ident. If "onlyOne" has the value "true",
addHandle removes from the message any fields with the specified ident before
adding the data pointed to by "handle". If no value is passed for "onlyOne," it
defaults to "true".

The "type" parameter lets advanced users specify the type of the field to be
added. This only needs to be passed if you are creating nontext fields that do
not occur on the send screen for this message type. In all other cases, the type
is filled in automatically.

This information is taken from the "Microsoft Mail HyperCard Interface
Documentation."
