Well, i'm probably not the only one to respond to this message, but here
goes:

You can use the execute function to perform operations on string
variables. Eg:

varlist=['var1','var2','var3']

for i=0, 2 do r=execute('print,'+varlist[i])

will print the contents of var1, var2, and var3. I find this a convenient
way to add callbacks to widgets on the fly, using a linked list of
string callback function names which are executed by the event handler.
