Hello Andrew,
I have file Q.csv:
C:\Temp>type Q
i,j,k,Q
1,1,1,""
1,1,2,1 3 4 5
1,1,3,1 5
1,1,4,1 3 5
and model test.mod
set I, dimen 3;
set J;
param Q{I}, symbolic;
table data IN "CSV" "Q.csv" :
I <- [i, j, k], Q;
solve;
display Q;
end;
I get unexpected error:
Q.csv:2: empty field not allowed
Why shouldn't Q[1,1,1] be read as a string of length 0?
This relates to the question by Krishna.
Best regards
Heinrich Schuchardt
