Re: Seekign help with MARC.pm ->as_string

(By MARC.pm, I believe you mean the MARC::Record distribution of modules).

According to the POD of MARC::Field, at "subfield(code)"

"When called in a scalar context returns the text from the first 
subfield matching the subfield code."

So, in  "my $phys_format   = $field->subfield('c');", $phys_format 
contains the text of subfield c, rather than a Perl object. Instead 
of:

if($phys_format->as_string() =~ /Paperback/ ){

(which, according to the error, is the same as saying 
"if(Paperback->as_string() =~ /Paperback/){")

This:

if($phys_format =~ /Paperback/ ){

should work.

The as_string method is used for entire MARC::Field objects (whole 
fields, with optional filtering to include only some of the 
subfields).
