&HD200

[Gopakumar Venugopalan]

Hello everyone what is command &HD200, if &HD378 is an address, what 
is that (&HD200) value referring to?
Thanks in advance.

Secondly, if I were to assign a trigger value to each MEG condition 
(Control, word, pseudoword) then do I simply list say 1, 9, 17 or 33 
in a column called "trigger" in the stimlist? Will that then tag my 
MEG files appropriately? Thanks in advance.
Warm regards
