Re: CHKOBJ in RPG IV programme

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Hello Carel,

I see that others have given you alternative solutions but no one has
explained your problem which is quite simple.  You have code the fourth
parameter as:

     D Aut             S             10    INZ('*NONE')

but the command allows a list of up to 10 values for AUT.  Since a CA
list is prefixed by a 2-byte count of the number of elements in the list
the QLICKOBJ program is interpreting the first 2 bytes of Aut as a
length.  *N is x'5CD5' which is decimal 23765 which is much longer than
the space available hence you cause it to walk off the end of your
available storage.

Define Aut as a structure, pass the DS, and it should work:

D AutDS         DS
D   len                 5I 0  INZ(1)
D   aut                10     INZ('*NONE')

C                   Call(E)   'QLICKOBJ'
C                   Parm                    Fullobj
C                   Parm      InType        ObjType
C                   Parm      InMember      Member
C                   Parm                    AutDS

Also QLICKOBJ is a system domain program which means you cannot call it
from a non-system state program when QSECURITY is above 30.

Also it is an undocumented interface and subject to change (although it
hasn't changed in years).

Regards,
Simon Coulter.
