        add-recipient [30] (( text-no       : Text-No;
                              conf-no       : Conf-No;
                              recpt-type    : Info-Type ))
                -> ( );
Adds conf-no as recipient to text text-no.  If
recpt-type is 1, then a cc-recpt (see The Misc-Info List) is created; otherwise a recpt is created.
Since protocol version 8 this call can also be used to change a
cc-recpt into a recpt and vice versa by simply adding
a recipient that already exists.
Since protocol version 10 the recpt-type parameter is a
Misc-Info.  Only infos recpt, cc-recpt and
bcc-recpt are accepted.  In protocol version 9 and earlier this
argument was a BOOL, that indicated if the recipient should be
a cc-recpt (when true) or recpt (when false).
Example:
        1 26 1
        =1 2 22 12 17 6 97 4 197 1 5 4 256 1 0 *
        1 30 1 5 0
        =1
        1 26 1
        =1 2 22 12 17 6 97 4 197 1 5 4 256 1
           3 { 0 5 6 1 9 34 34 17 17 6 97 4 197 1 }
        1 30 1 5 1
        =1
        1 26 1
        =1 2 22 12 17 6 97 4 197 1 5 4 256 1
           3 { 1 5 6 1 9 34 34 17 17 6 97 4 197 1 }
This example show how conference 5 is added first as a recipient of text 1, then changed to a carbon-copy recipient. The misc-info list reflects these changes.
login-first
undefined-conference
conf-no does not exist.
conference-zero
conf-no is zero.
no-such-text
text-no does not exist.
already-recipient
conf-no is already a recipient of the same type as
recpt-type.
illegal-info-type
recpt-type is not recpt, cc-recpt or
bcc-recpt.
