I don't know whether such casting is considered bad practice. Anyway, 
you should use the 'ptr' property of arrays instead, as it's cleaner.

     int ret = sscanf( line.ptr, ttempl.ptr, &min, &sec );

Check out http://www.digitalmars.com/d/1.0/arrays.html and look for 
"Dynamic Array Properties". You'll find it there.

Sorry, can't help you there.
