Re: Returning a pointer (was - parameters - const, value, reference)

Hi Rick, Scott,

Just to add a little to Scott's explanation of *NOPASS -- if one parameter
is prototyped with OPTIONS(*NOPASS), all the following parameters must also
have OPTIONS(*NOPASS), *and* the called procedure should be checking for
this with %parms or some similar method and acting accordingly (i.e. not
using these parms).
