CategoryGetSymbols( categoryWatchlist, Name of the watchlist?);

Any idea how can I fix a watchlist name to run.
I find only this

Listnum     = 1;  
list        = CategoryGetSymbols( categoryWatchlist, Listnum);

The watchlist has a name (string) instead a figure.
For example Techstocks
list = …
Thanks for answering my problem

listname = "Techstocks";
category = categoryWatchlist;
listnum = CategoryFind( listname, category );
list = CategoryGetSymbols( category, listnum);
