Question:
I often see configuration tips that show a whole string of commands, so that all of the parameters you want to configure are covered in just one command line.

For example, how use the CRDEVPRT command to configure a virtual printing device that uses a specified PSF-object for IPDS printing:

CRTDEVPRT DEVD(<DEVICE NAME>) DEVCLS(*LAN) TYPE(*IPDS) MODEL(0) LANATTACH(*IP) AFP(*YES) PORT(9100) FONT(11) FORMFEED(*AUTOCUT) RMTLOCNAME('192.168.0.97) USRDFNOBJ(AFP/NETWRKPRT *PSFCFG) TEXT('My IPDS Printer')

But there's not enough room in the dialog screen. What should I do if I want to use such a command line instead of paging my way through the dialog screens?

Answer:
Start by executing the command:

CALL QCMD

from a normal command line.

Press F11. This will open up an entire screen full of lines for typing in the command line.
