No, do not change the file names. Those with __define in their name
are files that define classes. The routines with :: in their names are
methods of those classes, and that is the way they should be.

First, make sure you have in your IDL path all the source code files:

http://www.ppenteado.net/idl/pp_editablecube__define.pro
http://www.ppenteado.net/idl/pp_readcube__define.pro
http://www.ppenteado.net/idl/pp_setcubeheadervalue.pro
http://www.ppenteado.net/idl/pp_extractfields.pro
http://www.ppenteado.net/idl/pp_getcubeheadervalue.pro
http://www.ppenteado.net/idl/pp_buffered_vector__define.pro

Then, what exactly were you trying to do?

This (copied from the file pp_editablecube__define.html) is one
example of how to use it to read, edit and write a cube:

To initialize from the cube CM_1553510065_1_ir.cub:

a=obj_new('pp_editablecube',file='CM_1553510065_1_ir.cub')

To add a dummy backplane:

a-
> getproperty,backplanes=back,backnames=bnames,lines=lines,sam ples=samples
backplanes=[[[backplanes]],[[findgen(lines,samples)]]]
backnames=[backnames,'DUMMY']
a->setproperty,backplanes=back,backnames=bnames

To remove the first core band:

a->getproperty,core=core,wavelengths=wavs
core=core[*,*,1:*] & wavs=wavs[1:*]
a->setproperty,core=core,wavelengths=wavs

To add lines to the history part of the header:

app=['GROUP = testedit','date = '+strcompress(systime(),/
remove),'END_GROUP = testdate']
a->headerset,append=app

To write the edited cube to 'testedit.cub':
a->write,'testedit.cub'

Destroy the object when done with it:

obj_destroy,a

There are more examples, for reading thing from a cube, in the file
pp_readcube__define.html.
