Here is a method similar to how I do it in the QT external.  This is 
based off of some code Tuviah sent me.

int retvalue = 0;
char	mcmessage[1024];

SetGlobal("myGlobalVariable",tmessage,&retvalue);

snprintf(mcmessage, 1024, "global myGlobalVariable;try;send \"%s 
myGlobalVariable\" to %s in 0 seconds;catch errno;end try;put 0 into 
myGlobalVariable", messagename, objectname);

SendCardMessage(mcmessage, &retvalue);

Where objectname, messagename nad tmessage defined as char *.
