Exactly ...
you just avoided a "halt" due to undefined env setting :)

And even if you (as the admin or through /usr/share/skel/*) set it once and 
forget about it, every user would still be able to set/override his preferred 
default paper/page size via .cshrc or the like just as we decide whether to 
use "less" or "more" as a pager ;)

So paper/page size would be determined at app run time on a case by case 
basis :)

As a side effect, we just took the burden of letting devels decide 
what "default" action should be ... if no arg is given, switch to default, 
which will read the value assigned to PAGESIZE or resort to en_US to default 
to "letter" or A4 if else, should PAGESIZE not be defined.

As a consecuence, those who have en_US will always have "letter" as default 
(regardless of whether they set PAGESIZE or not). And the rest of us will be 
happy with A4 or would still have the chance to set PAGESIZE=letter.

And best of it all is: app default behaviour never changed !
The only diference is that it will read an env before acting ... that 
env "changes" the way the app behaves. But that change is transparent to the 
user ;)

Well .. I think that makes two of us now :D
