You can't wrap the SYSTEM.VAL function because it is implemented in the 
compiler. There's no way to pass type parameters to Oberon-2 procedures; 
although OOC supports generics, this only works for Object types. I 
think the solution you suggested is probably the best option, though as 
you say it is not ideal.
