Re: Indicator name

I haven't done display files in quite some time, but instead of doing a
DSPATR(RI), you can do a DSPATR(&DSPFLD1) where &DSPFLD1 is defined as a
program field in the DDS. Then in the RPG program you set the DSPFILD1
value with the hex representation of the attribute
http://wiki.midrange.com/index.php/Program_To_System_Fields

In the long run this may be correlated to your issue, but if not, maybe
it's a future consideration for setting the display attribute.

Best of luck,
Kurt

I thought about doing that.
The big drawback is if a field is added to the screen with an indicator to
reverse image and position cursor.
Makes maintenance a nightmare and if someone goes into SDA brings up the
screen, f4 f6 to sort the buffer may change!
Now the programmer will have to know the buffer positions.
I wanted to make this so any programmer (newbies included) can pick it up
and easily maintain it.
You are suggesting this:
D Out02 ds LikeRec(Maint02:*OutPut)
D ProtectStatus 2 2N

Since this is the entire output buffer, I guess that's the only solution.
I'll stick with out02.in33 = *On in that case. (it's easier to remember
indicators than buffer positions)

Thanks,

Craig

Overlay a name in the DS.

Sonethink like this

D Previous...
D e Ds Qualified ExtName(CF9999P :*INPUT)
D prefix(a)
D Changed_Data 38 568

RE: Indicator name






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).

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

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
