Hey,
If I run (PDL-2.018)


#!/usr/bin/env perl
use PDL::IO::Misc;

my @cols = rcols('data.dat', {EXCLUDE => '/^#/'});

I get

simon@buero ~/perl/lab (master)$ ./rcols.pl
Undefined subroutine &PDL::Ops::assgn called at /home/simon/.plenv/versions/5.24. /lib/perl5/site_perl/5.24.0/x86_64-linux/PDL/Core.pm line 810, <GEN0> line 2.

The error disappears when adding use PDL or use PDL::Lite

Could you provide a small data.dat that gives the problem? Thanks.

you can just use a file that contains a single ascii number.

The reason that error is coming up is that PDL::Ops is never used directly in Misc.pm. Since the docs for PDL::Lite say that PDL::Lite is the minimum required to required to have a working PDL, and that is not present in the example code, I'm going to close this as not-a-bug.
