[Cmpl] Question about readcsv and multi-dimension arrays

[Michael Bond]

I'm just getting started with CMPL and have what seems like a rather basic question. Given the following CMPL model how what should the csv for r be formatted:

    parameters:
        plants := "seattle", "san_diego"
        markets := "new_york", "chicago", "topeka"
        r[plants, markets] := readcsv("r.csv");

Using the following in r.csv:

2.5,1.7,1.8
2.5,1.8,1.4

I get the following errors:

error (interpreter): file transport.cmpl line 9: Count of elements for the 1. index of 'r' is wrong
error (interpreter): file transport.cmpl line 9: Count of elements for the 2. index of 'r' is wrong

Using the following in r.csv:

new_york,chicago,topeka
seattle,2.5,1.7,1.8
san_diego,2.5,1.8,1.4

I get the following errors:

error (interpreter): file transport.cmpl line 9: Count of elements for the 1. index of 'r' is wrong
error (interpreter): file transport.cmpl line 9: Count of elements for the 2. index of 'r' is wrong
error (interpreter): file transport.cmpl line 9: Count of elements for the 2. index of 'r' is wrong
error (interpreter): file transport.cmpl line 9: Count of elements for the 2. index of 'r' is wrong

I've tried a number of other variations with no success. I've seen the readcsv examples that use an unbounded array (r[,]) but for would prefer to use bounded arrays. Any help would be welcome.
