Are you properly combining the addresses is the command? If you prompt it (F4), that should set it all up for you. I don’t have a BCC example, but I do have an example of sending to multiple addresses:
<pre> snddst type(*doc) tointnet((email@example.com *pri) +
(firstname.lastname@example.org *pri)) dstd(‘Blah +
Blah Blah’) msg(‘Yada Yada +
Yada’) pty(*high) +
doc(&file) flr(‘folder’) subject(‘sample for +
You should be able to change either of the ‘*pri’ entries in the above format to ‘*bcc’. But, note that they are individually parenthesized within the ‘tointnet’ parenthesis!
