Example 1:

Assume a system has the following characteristics:
Issue the following command:
D IPLINFO
The system returns the following display, slightly modified to improve readability:
IEE254I  11.14.07 IPLINFO DISPLAY 350            
 SYSTEM IPLED AT 01.15.39 ON 12/01/2006          
 RELEASE z/OS 01.08.00    LICENSE = z/OS         
 USED LOAD08 IN SYS0.IPLPARM ON ACB2             
 ARCHLVL = 2   MTLSHARE = N                      
 IEASYM LIST = (X6,U6,0L,R8)                     
 IEASYS LIST = (ST,LN) (OP)                      
 IODF DEVICE ACB2

Example 2:

Assume that you specified (or defaulted to) ZAAPZIIP=YES. Issue the following command:
D IPLINFO,ZAAPZIIP
The system returns the following display:
IEE255I SYSTEM PARAMETER 'ZAAPZIIP': YES

Example 3:

Assume that you specified (or defaulted to) ZAAPZIIP=YES but ZAAPs are assigned to this LPAR. Issue the following command:
D IPLINFO,ZAAPZIIP,STATE
The system returns the following display:
IEE256I ZAAPZIIP STATE: INACTIVE - ZAAP(S) DEFINED TO THIS LPAR
