Answer Wiki:
If you mean, how do you change the system-supplied qpquprfil file so that it uses different outq/forms/other attributes, you would simple use the prompted CHGPRTF command and change whatever printer file parameters you wanted. You would have to repeat this change process every time you put up a new release of OS/Query.
If you wanted to change it for just a single run instance, you would override it with a OVRPRTF command, again specifying the parameters of interest.

Hi,
Best to use the OVRPRTF option for this.
It’s never a good idea to change the system-supplied objects. If you do, then every time you upgrade the OS, you’ll need to go through and change them all again. Then you wonder which ones you changed, how many of them you changed, not to mention exactly which parameters you changed.
If you can keep to using overrides, then you won’t need to do this.

Actually, it is easy to keep track of changed objects with a little organization. We have placed an IBM_CHANGE library high in the system library list to avoid redundant programming efforts.
Hi,
The idea of an IBM_CHANGE library is ok for most things, but you can still get problems with this when you get OS upgrades.
For example you want to change the standard attributes of one of the system supplied print files, so you take a copy to your IBM_CHANGE library and change the attributes of your copied print file. Along comes a new OS upgrade, with a new version of the print file – any programs that use this print file will find your *old* version of the print file instead of the new one. The OS programs that use this print file may crash or dump, until you remove your copied print file or replace it with a copy of the one from the new OS (with your attribute changes re-aplied).
Personally I think it’s best to avoid changing system objects as far as possible.
Cheers,
Martin Gilbert.
I agree with the principle of avoiding changes to IBM-supplied objects. If it needs to be done, it’s best to do it to a duplicate and use the library list to access the necessary version.
Create the duplicate and apply the change together in a CL program. Add statements to that same program for each changed object. When upgrading the OS, run that program after the upgrade completes in order to capture new versions from the upgrade and to apply your changes to those new duplicates.
This keeps track of changes and helps recover them later.
