Joep,
You can supply the file name and library as variables, just declare a
variable as a data structure and break it apart; it's RPG IV, not Rocket
Science.
On another note, if you use EXTFILE and/or EXTMBR remember that THESE ARE
NOT OVERRIDES. They are direct opens of the specific file/member. So you
don't get the same side-effects as issuing an OVRDBF command. That is,
there's no SHARE(*YES) or SEQONLY(*YES) capability. Those options still need
to be issued via an OVRDBF command.

Well, USROPN is not that new; even RPG III had it (UC somewhere in the
F-spec). 
Besides, using QCMDEXC from within RPG for issueing an override is not much
use 
without USROPN (unless you do it for a call to another program). As for
EXTFILE: 
so far I have not made much use of it. Most overrides in our applications
fall 
in two categories: SHARE(*YES) for OPNQRYF and MBR(&USRID) for multi-member
work 
files. For the first category EXTFILE is no use; for the second category we 
could use EXTMBR when we pass &USRID as a parameter. The debate about that
one 
is still on :-) Apart from that I find the syntax of EXTFILE cumbersome; it
is a 
pity you can't supply filename and library as separate parameters.
