After I hit send I realized that in this case you don't need the pointer. You could define the DS like:
D sqlData DS
D k00001 21A
d c@ 1 5 0
d typi 6 6 0
d fschi 7 7 0
d cyci 8 8 0
d arrRT 3 0 dim(7)
I almost always define a sqlData structure, because it is usually eaiser to get the pre-compiler to accept it. You can then do anything you like with it, including using a pointer to allow you to put the data anywhere you want/need, Eg.
D pending DS Qualified
D Static
D static
D count 10I 0 Overlay(static)
D Inz(0)
D data LikeDs(sqlData)
D Dim(100)
D sqlData DS Qualified
D Dim(100)
D Based(sqlDataBase)
D id 20I 0
D djde 100A Varying
D idx 100A Varying
D pdf 100A Varying
sqlDataBase = %Addr(pending.Data);

BINGO!
That was exactly what I needed!
It gave me the concept that I could adapt to the live situation.
Awesome, Duane! You da man!

Why not do this:
D sqlData DS
D k00001 21A
D record DS Based(recordBase)
D... (your original definition here)
recordBase = %Addr(sqlData);
sqlstm = 'select SubStr(K0001, 1 , 21) +
from qs36f/"DS.SCH"';
...
exec sql
fetch C1 into :sqlData;
...
This will put the first 21 bytes of data into sqlData, which is "overlaid"
with by the record DS.

Thanks for the reply Michael.
This causes the SQL pre-compile to fail with the error:
MSG ID SEV RECORD TEXT
SQL0312 30 787 Position 27 Variable SCHRECORD not defined or not
usable.
I suspect it compares the number of fields in the DS versus the number in the fetch and barfs all over itself. Perhaps it thinks that the overlay is an additional field.

change
d arrRT 3 0 dim(7)
To
d strRT 21
d arrRT 3 0 OverLay(strRT) dim(7)
I haven't tested, but it's worth a try.

Dynamic SQL fetch into an array

After beating my head against this issue, I've searched the archives and the Internet with no luck. I am attempting to fetch a record in embedded SQL and this record includes a 7-element array. I'm fetching from a program-described file (QS36F).
I've oversimplified the code below - I just need to get the basic concept.
d SchRecord ds
d c@ 1 5 0
d typi 6 6 0
d fschi 7 7 0
d cyci 8 8 0
d arrRT 3 0 dim(7)
sqlstmt = 'select +
substr(K00001,1,5) as c@, +
substr(K00001,6,1) as typi, +
substr(K00001,7,1) as fschi, +
substr(K00001,8,1) as cyci, +
substr(F00001,1,21) as arrRT +
from qs36f/"DS.SCH"
exec sql
prepare P1 from :sqlstmt;
exec sql
declare C1 cursor for P1;
exec sql
open C1;
dou sqlstt <> '00000';
exec sql
fetch C1 into :SchRecord;
if sqlstt <> '00000';
leave;
endif;
Etc.
The other fields read in properly but "arrRT" reads in as a single 3-digit field instead of an array of seven 3-digit elements. I defined it as an array in the DS - why does SQL ignore that?
I have to do this as dynamic because of the "where" and "order by" clauses that are needed.
Any thoughts are appreciated. I'm starting to feel like Danny Noonan in Caddyshack ("right in the lumber yard").
