Thank you for your bug report.

However I see no bug. The following example works for me:

---test.mod---
set V;

param d{V, V};

table data IN "CSV" "test.csv": [FROM, TO], d~DISTANCE;

display d;

data;

set V := Seattle San-Diego New-York Chicago Topeka;

end;

---test.csv---
FROM,TO,DISTANCE,COST
Seattle,New-York,2.5,0.12
Seattle,Chicago,1.7,0.08
Seattle,Topeka,1.8,0.09
San-Diego,New-York,2.5,0.15
San-Diego,Chicago,1.8,0.10
San-Diego,Topeka,1.4,0.07
