That's reasonable.

by commenting out fields that I am not interesed in. 


But that is not.

How can I make this work?
%fields = (
    lastname => $fieldnum++,
    firstname => $fieldnum++,
#    middlename => $fieldnum++,
    userid => $fieldnum++,
    rscname => $fieldnum++,
    email => $fieldnum++,
    roleid => $fieldnum++,
)



Remove the '#' and add some code to remove the keys you don't
want.  That is, change the hash dynamically at runtime instead
of constantly editing the source code.

delete $fields{middlename} if $ignore_middle_name; 

Wouldn't it be easier not to create the value in the first place?

%fields = (
    $do_lastname  ? (lastname => $fieldnum++)  : (),
    $do_firstname ? (firstname => $fieldnum++) : (),
    ...
)
