====== Assign cannot have a return value ======

VO unfortunately permits to return a value from an ''assign''. Since this is not permitted in .NET, the X# compiler will return an error of
<code>Warning XS9032 This entity type cannot return a value. Return value ignored.</code>

The following code, perfectly valid in VO, will throw this warning in X#:
<code visualfoxpro>class MyClass
  protect _cMyVar as string
  
assign MyVar( cMyVar ) class MyClass
  _cMyVar := cMyVar
  
  return _cMyVar</code>
  
It is recommended to type the access/assign pairs in VO, like this sample:
<code visualfoxpro>class MyClass
  protect _cMyVar as string
  
  declare assign MyVar  
  
assign MyVar( cMyVar as string ) as void pascal class MyClass
  _cMyVar := cMyVar
  
  return</code>
In this manner the compiler will you notify when you anywhere in your code have used the return value of the ''assign'' statement. (other than giving you faster and more stable code)
