Also, if you are using emacs with idlwave then you can change the size
of the history by changing the variable 'comint-input-ring-size' - see
"Idlwave Shell Command History File" in Customize->Idlwave Shell
Command Setup.

Thanks for your advice. But it's the same as with Mark's one: Seems like
my idlwave / emacs-combination doesn't know that particular
configuration option. Upon your hint (being not very familiar with the
zillions of emacs configuration options), I found the IDLwave group in
the configuration menue and checked every single one within that
category and its subcategories, but without success. There doesn't seem
to be an option relating to the command history :(
I'm starting to think there's something weired, but all is basically the
defaults, both IDL and emacs. :(
Best regards,
Ingo

To be pedantic:
IDL> print, pref_get('IDL_RBUF_SIZE')
20
IDL> pref_set, 'IDL_RBUF_SIZE', 200, /commit
IDL> print, pref_get('IDL_RBUF_SIZE')
200
IDL> exit
$ idl
IDL> print, pref_get('IDL_RBUF_SIZE')
200
