RTVOBJD2 RETRIEVE OBJECT DESCRIPTION 2 TAAOBJW
The Retrieve Object Description 2 tool is designed for HLL program
use to retrieve the description of an object. An externally
described data structure is used to both pass the ID fields (object,
library, and object type) and return the description fields. The
program TAAOBJWR must be called and passed the externally described
data structure. No command exists.
You may review the fields in the Externally Described Data Structure
with the command:
The system QUSROBJD API is used by TAAOBJWR to retrieve the
The following code is in a format to be copied directly into an RPG
program and shows how the tool would be used. First use CPYTAA
TAAARCMBR(RTVOBJD2) to copy the source for this documentation member
to QATTINFO in TAATOOL.
I* OBJRCD is defined by the RTVOBJD2 TAA Tool
IOBJRCD E DSTAAOBJWP
I 'TAATOOL/TAAOBJWR' C RTVOBJ
C* Move fields and call RTVOBJD2 tool.
C MOVELxxx ODLBNM Lib name
C MOVELxxx ODOBNM Obj name
C MOVELxxx ODOBTP Obj type
C CALL RTVOBJ
C PARM OBJRCD
C* Fields such as ODOBAT, ODOBSZ, etc are now avail to use
If the library name is blank, *LIBL is used. ODLBNM is set by the
program to be the library where the object was found. The value may
have changed when the program returns.
If the object does not exist, CPF9898 is sent as an escape message
with the message text as received by the TAAOBJWR program.
Most of the field names used are the same as in the DSPOBJD outfile
such as ODOBNM. The date fields are returned in YYMMDD format in the
externally described data structure which differs from most of the
outfile date definitions of MMDDYY. The ODOBSZ (object size field)
is defined as *DEC LEN(15 0) to account for large object sizes. For
most of the other field names, the attributes and meaning of the
values are the same as in the DSPOBJD outfile.
Note that for ILE programs, neither DSPOBJD, RTVOBJD, nor RTVOBJD2
will return information about the source used.
The TAAOBJWP externally described data structure has a reserved area
to allow for a reasonable amount of growth for new fields without
impacting existing programs. If additional fields are added that do
not exceed the size of the reserved field area, there is no reason to
re-create an existing program that uses the externally described data
structure unless the information from the new fields is needed.
Command parameters *CMD
No command exists.
The following TAA Tools must be on your system:
HLRMVMSG HLL Remove message
RPGSTSDS RPG status DS
SNDESCMSG Send escape message
None, the tool is ready to use.
