I wanted to do much the same thing a while back.

Unless I am very much mistaken, there is no way to assign a string to a 
convenience variable. The nearest you can get is to place it in the 
inferior program's memory somewhere (perhaps using malloc, or some fixed 
location) and then assign a pointer to the variable. Obviously you can't 
do this until there is some memory to write to. However, you could 
extend the patch to expect a 'char *' variable for the name.

Also, all convenience variables are wiped by the file and symbol-file 
commands (because their types disappear along with the old symbol 
table), so they aren't that convenient for scripting this kind of thing.
