1. To check File object, you should defined file in User
open mode and by using %Open operation we can identify the
file object is present or not.
2. To check Program object,
Use MONITOR; opcode or in calling specify low indicator, if
Low indicator is On, means object is not present in library
list.

The question is:
How can i check the object existence in RPG program without
using QCMDEXC command?
Answers posted by AS/400 experts:- use Monitor On error; what if file is not in user opened mode and already declared & opened in F specs...this solution will not work in this case and program will throw error when it tries to open the file in F specs itself...(This we can solve using File Information DS)
User wants to know the object existence, it (object)can be file object, program object or any other type of object.
Generally we check object existence by using CHKOBJ command but user said not to use QCMDEXC API...
The solution is(by using QUSROBJD API):
*---------- Global variables: ----------------------*
D ObjNam s 10a
D ObjLib s 10a
D ObjTyp s 10a
*---------- Api error data structure: --------------*
D ApiError Ds
D AeBytPro 10i 0 Inz( %Size(ApiError))
D AeBytAvl 10i 0 Inz
D AeMsgId 7a
D 1a
D AeMsgDta 128a
*-- Retrieve object description: -----------------------*
D RtvObjD Pr ExtPgm('QUSROBJD')
D RoRcvVar 32767a Options(*VarSize )
D RoRcvVarLen 10i 0 Const
D RoFmtNam 8a Const
D RoObjNamQ 20a Const
D RoObjTyp 10a Const
D RoError 32767a Options(*VarSize)
C Eval ObjNam = '???'
C Eval ObjLib = '*LIBL'
C Eval ObjTyp = '*PGM'
*
C CallP RtvObjD( RoData
C : %Size( RoData )
C : 'OBJD0100'
C : ObjNam + ObjLib
C : ObjTyp
C : ApiError
C )
*
C If AeBytAvl > *Zero And
C AeMsgId = 'CPF9801'
*-- Object doesn't exist...
C EndIf
*
C Return

Answer / mithila
In RPG4, QusRtvObjd API can be used which has procedutrs
like ChkObj and ChkMbr. or a CL program can be called that
checks the existence of object and returns some indicator
to for found/not found.
