I don't think you are understanding my problem.
I can't just turn on *IN33 or use indds, that won't work since I am writing
with the output buffer.
Here is an example:
// write output buffer and read input buffer
Write Maint02 Out02;
Read Maint02 In02;
Eval-Corr Out02 = In02;
I have to move *ON to out02.in33 to make the protect work.
I want to use a named indicator instead of out02.in33 (buffer name).

Subject: Re: Indicator name
This is from a document I put into our tips and techniques. Hope it helps.
Using Named Indicators
The last bastion of indicators in RPG is display or print indicators.
You can use p fields to set display attributes but, for example, to display
a subfile or subfile control, you need to use indicators but what the hell
does
*IN27 = *On;
mean in a program?
Wouldn't
DisplaySubfileControl = cTrue;
make more sense?
To do this we use the keyword INDDS on the display file spec.
fTG0002_D01cf e WorkStn InfDS(FI01)
f UsrOpn
f IndDs(dsIndicators)
f Include(RD01_01 :
f SFMSG_CTL)
Next we have a copy block (CB_MAP_IND in ILPGMR/QSRCF) that contains the
following.
d dsIndicators ds
d IndicatorArray...
d Like(StdLgl)
d Dim(99)
Just put /copy *libl/qsrcf,cb_map_ind in your program.
Finally we add a statement after the copy block to do the map.
d DisplaySubfileControl...
d Like(StdLgl)
d Overlay(dsIndicators:27)
We can know refer to the indicators by the name.
DisplaySubfileControl = cTrue;
Or
If DisplaySubfileControl;
Etc.
The complete structure definition. Note that there are no "s" in the field
types which means these just extended the existing data structure.
/copy *libl/qsrcf,CB_MAP_IND
d DisplaySubfileControl...
d Like(StdLgl)
d Overlay(dsIndicators:27)
d DisplaySubfile...
d Like(StdLgl)
d Overlay(dsIndicators:28)
d ClearSubfile...
d Like(StdLgl)
d Overlay(dsIndicators:29)
So now you don't need to use an indicator. You can use a name.

I'm writing a program (green screen) that uses a write and read
with a data structure name to the workstation.
Actually I'm trying to write this program as a skeleton program for
the rest of the programmers on staff.
I am using Eval-Corr to move data back and forth from input, output,
and disk (using likerec).
Is there a way to rename an indicator in the output buffer?
Right now, I have to Out02.in33 = *On; to protect a screen field on
add (33 protect n33 underline in dds).
I would like to use a named indicator like ProtectStatus.
Any suggestions?
Thanks in advance,
Craig
