bug? substitution in shipping.asc

[Kyle Hayes <kyle540@quicknet.net>]

I have been running tests on what shipping.asc can do.

I am trying to add a routine to calculate insurance for UPS shipping
without any success.

I have it calling my routine correctly, but it does not pass @@COST@@ as
the manual indicates should be done.

the call is:

ups_insurance('1',@@COST@@,'2',@@ADDER@@,'3','23.0')

"ups_insurance" is a GlobalSub implemented in minivend.cfg.

When I dump @_ in ups_insurance to the log, I get:

	args: 1 2 3 23.0
	num args: 4

Now, there are couple of things that worry me.  First, I should be seeing
something for the @@COST@@ etc. fields.  I am not seeing anything at all.
Second, the number of args returned is 4 not the expected 6.  If I put
single quotes around the @@ variables, I get null strings (but not null or
undef) back.  

According to the manual, @@COST@@ should be replaced by the value returned
from the UPS look-up routine.  It looks like it is returned as undef or
something.

I tried the @@ADDER@@, @@COST@@ and @@GEO@@ tags to see if they do
anything.  So far, none of them return any values that I can discern.  

I tried checking to see if I get references back, and I don't.  So, as far
as I can tell, this is a bug.  The tags with @@ are getting parsed in some
manner because they aren't passed along.  But, no values are substituted
for them.

This is with MV 3.14 on Red Hat Linux 6.0.

This one is getting frustrating.  

Best,
Kyle
