I am debugging a large program I didn't write. At some point in the code, it prints GLOB(0xstuff) a bunch of times. The stuff is a hex number, presumably a mem address on my computer.

I am wondering what kind of structure one has to print in order to get this result. I tried printing references without dereferencing them, but that gets me HASH(0xstuff) ARRAY(0xstuff) and SCALAR(0xstuff), depending on what kind of reference I use.

I am running 5.8.1 on Redhat 9, though the code was originally written under 5.6.x on Redhat 7.3.

Please give me a hint, like some sample code that prints this type of output, or refer me to the correct section of TFM (I couldn't find it in perldoc).
