Hello Nigel,
>>Is it possible to spread a table over 2 data files, obviously with
different tuple ID's.
A statement may not exceed the file end.
You can use a union of sets for your purpose.
t.mod
====
set S{1..2};
set U := S[1] union S[2];
display U;
end;
d1.mod
=====
data;
set S[1]:= b1 b2 b3;
end;
d2.mod
=====
data;
set S[2]:= a1 a2;
end;
$ glpsol -m t.mod -d d1.dat -d d2.dat
Display statement at line 3
U:
b1
b2
b3
a1
a2
Best regards
