generic call backs

generic call backs

[Ewan Benson]

Hi,

I'm posting this for a (remote) colleague who doesn't have access to the net 
at present (and I haven't seen a FAQ for this group) so here goes.

He has two packages A and B

Package A contains a 'with B'

Package B contains a call to a subroutine in A, but for his own reasons he 
does not want to use a 'with B' in package A. He's convinced it can be done
but can't find any info in his Booch reference.

Any help in this direction would be gratefully received

Thanks for your patience

Ewan (going back to comp.lang.c and the int main (void) flames !!)

Under VAX Ada, you can have circular with statments, but to compile,
you must load one into the library (load only does a syntax check I think),
then do a recompile.

By the way what kinda set up are you working under???

Are you really saying that Dec Ada allows two package specs to with one
another? surely not, this is a clearly illegal program, which any Ada
compiler should be expected to detect and disallow.

I hate to say this Robert, but this is a dumb question.  You of all people
should know better than to even ask this.

"I hate to say this Robert, but this is a dumb question.  You of all people

fine, it's a dumb question, but that's what I took someone to say, and I
still don't know if I am being dumb because the answer is "of course Dec
doesn't allow this", or because it is obvious from the original post that
Dec does allow this. I trust it is the first, but I do not have ESP! As
my original post makes clear I hope, I would be amazed to find that Dec
allowed this, even with the peculiar special switch that was mentioned
in the original post.
