  - get
```
public VncVal get(VncSymbol sym)
```
    Look up a local or global symbol's value
    Unqualified symbol resolution:
    1. try to resolve the symbol from the local namespace
    2. try to resolve the symbol from the global current namespace defined by *ns*
    3. try to resolve the symbol from the global 'core' namespace
    Qualified symbol resolution:
    1. qualified symbols are resolved exclusively from the global symbols
    Parameters:
    
    sym - a symbol
    
    Returns:
    
    the value
    
    Throws:
    
    VncException - if the symbol does not exist.
