[Cmpl] Problem when sets contain numeric values as strings and 'long line name' situation

[Maria Giatsoglou]

Hi Mike,

I have encountered the following situation with CMPL:

In my model I am importing the following parameters set from a cdat file

%M set[3] <
"7" "2" "10"
"1" "12" "7"
>

Then, I use this set in the following expression

flag := 0;

it {[i,j,k] in M, i != "off", j != "off", k != "off":

         flag:= 1; break;

}

By doing this I get the following error: "Implicit type conversion from
string to integer is not possible".
I thought that by using double quotes, the values of set M would be
interpreted and treated as strings in CMPL (as was my intention), but I
found out that using

%M set[3] <
"7" "2" "10"
"1" "12" "7"
>

or

%M set[3] <
7 2 10
1 12 7
>

makes no difference.

Is there a way to circumvent this issue?


Additionally, when I try to solve my model I get the following error
message:
"Line name 'fm[3835],[1],[2]' is too long"
Can I somehow change the maximum line name length in CMPL?

Thanks!

My warmest regards,
Maria Giatsoglou
