Suppress output of rfits

astroman has asked for the wisdom of the Perl Monks concerning the following question:

Hello Perl Monks! Is there a way to silence the output of rfits calls in PDL? Every time I read an image, I get to see

Reading IMAGE data...
BITPIX =  -64  size = 1024 pixels 
Reading  8192  bytes
FITS file may contain bad values.
BSCALE =  &&  BZERO =
[download]

which becomes rather tedious after a while. As far as I can tell, rfits should only display this if $PDL::Verbose == 1... I've tried manually setting this to 0 by $PDL::Verbose = 0; but to no avail. Please help ease my frustration!

AFAICT, that should work, which version do you have? PDL::verbose `sub _rfits_image($$$$) { print "Reading IMAGE data...\n" if($PDL::verbose);` [download]	[reply] [d/l]

You solved it: I had been using a capital V for "verbose" because it appeared that way on the reference I'd found. Setting `$PDL::verbose = 0;` works great! Thanks!	[reply] [d/l]
