[comp.lang.ada] Accept with parameters but no do-end?

gore@nucsrl.UUCP (Jacob Gore) (11/06/86)

From ALRM 9.5, paragraph 21:

  "An accept statement need not have a sequence of statements even if the
   corresponding entry has parameters.

So, the following statement is legal:

   accept AN_ENTRY (A_PARM: A_TYPE);

Could somebody tell me why?  What would this be used for?  What's the scope of
A_PARM?
