Re: DEFINE *DTAARA Confusion.

Thank you for your input. @BILDS is not on the system either.

The calling program has the exact same thing in it. The DSPECS, the
DEFINE, but has an OUT @BILDS opcode.

The issue is arising because I'm writing a new program where I need to get
the data from this UDS. Originally, I had

D @BILDS UDS
D @@BILL 1 7 0
D @@SSEQ 8 10 0

/free
In @BILDS;
*inlr = *on;
/end-free

Compiler says that @BILDS is not a data area.

"The Factor 2 operand of IN or OUT is not a data area"

But I can get the program to compile if I add Dtaara(ODKEYS) to the dspecs.

D @BILDS UDS Dtaara(ODKEYS)
D @@BILL 1 7 0
D @@SSEQ 8 10 0


Wow strange, ODKEYS is coming from somewhere, just not sure where. Maybe a
user defined type? but wouldn't that be on the system somewhere?

I am guessing you don't need that line in the program anymore but it may
have been used at some time in the past. I am pretty sure you won't find
any IN or OUT statements using ODKEYS.

The key to what is happening is the U in the data structure definition.
An edited excerpt from the manual:

U defines a Data-area data structure.
-RPG IV retrieves the data area at initialization and rewrites it at end of
program.
- If the DTAARA keyword is not specified, the name in positions 7-21 is
used as the name of the external data area.

So I would think you have a data area on the system named @BILDS that is
read at the beginning of you program and written at the end automatically
for you.

Subject: DEFINE *DTAARA Confusion.

I'm looking at some code that is very confusion to me.

In a routine that is never called (actually named NEVER), there's this
line...


C *DTAARA DEFINE ODKEYS @BILDS

From what I've read is that ODKEYS is supposed to be an external data

structure. However, it doesn't exist on the system whatsoever. ODKEYS is
not a field within the program anywhere, and it's not being built on the
fly in QTEMP or anything. I'm just totally lost.

Before I go any further... @BILDS is defined in the DSPECS.

D @BILDS UDS
D @@BILL 1 7 0
D @@SSEQ 8 10 0


Maybe I'm reading too much into this. But I don't see how the program
compiles when it doesn't know what ODKEYS is. The program does compile.
Could it be some global variable or system variable? I don't know just
throwing it out there.

Any help would be appreciated.
