A capability similiar to this already exists.  I don't know at what version
it started, but DSPATR can accept a field name for some of the display
attributes.

See
http://publib.boulder.ibm.com/pubs/html/as400/v4r4/ic2924/info/db2/rbafpmst2
67.htm
for a list of the supported and unsupported attributes.  Essentially all of
the output-only attributes plus protected can be specified, input attributes
except protected cannot be specified.  In particular, position cursor cannot
be specified, which is a pain.  But it's a step in the right direction.

Here is real-life DDS ...

     A            #MAPRD#01      9  0B 10 16CHECK(RB) EDTCDE(Z)
     A                                      DSPATR(&@MAERR#01)
     A  71 81                               DSPATR(PC)
 ...
     A            @MAERR#01      1   P
There are 40 of the above sets of fields.

Here is real-life RPG IV ...

     d #dspul          c                   const(x'24')
     d #dspulri        c                   const(x'25')
 ...
     d                 ds
     d @maerr#                 1     40    dim(40)
     d   @maerr#01             1      1
     d   @maerr#02             2      2
     d   @maerr#03             3      3
 ...
     d   @maerr#38            38     38
     d   @maerr#39            39     39
     d   @maerr#40            40     40
 ...
     c                   eval      @maerr# = #dspul
This sets all of the 40 fields to underline.
 ...
     c                   eval      @maerr#(@x) = #dspulri
     c                   eval      *in($$$rowind(@x)) = *on
     c                   eval      *in($$$colind(@x)) = *on
@x points to an element in the array of product numbers which has an error.
The first line sets the field attribute to underline and reverse image.
This is very close what you are asking for.  No indicators involved.
Since position cursor is not supported, the next two evals call
subprocedures in the program to turn on indicators in a matrix pattern.
