in reply to format declaration in a class

Declare your format variables with either vars or our and then within the loop use local e.g
use vars qw($sku, $description, $price, $qty); foreach my $item (@items) { local($sku, $description, $price, $qty) = @$item; write(PURCHASEORDER); }
Or you could fully qualify your variables in your format and localize the appropriate variables i.e
use strict; format STDOUT = @<<<<<<< $::foo . local $::foo = 'a string'; write STDOUT; __output__ a string
Or you can declare the lexicals before the format, if that's feasible. See. perlform for more info.

    Hi and thanks for your help. The use vars seems to work fine, although when I tried our (in fact I tried it first before I posted to, I got (and continue to get) these errors:

    Variable "$sku" is not imported at lib/ line 206
    Global symbol "$sku" requires explicit package name at lib/ line 206.

    So my only solution (I guess?) is to use vars.
    I'm going to do more research to figure out exactly what that does. Thanks a lot! Update: Well I was mistaken, I need to put the our declarations external to a sub. In which case it works perfectly. Thanks again!
