hi,
i have  the following declaration in my opl model:

[b]range Trips = 0..card(RawTimetable)+card(Location)-1;
int Origin[trips] = ...; [/b]

when i try to assign this variable from my c# code by implementing the CustomOplDataSource class, it give me an error (variable dosnt exist),but when i change the declaration as following:
int [b]Origin[0..81] = ...;[/b] it works, my problem is how i can make it dynamic, i mean to declare the range by using a variable ([0..x]) and not a number ([0..81])???

thank you

Hi,

if you want to set some data thru CustomOplDataSource, then this data has to be defined in the .dat and not only in the .mod as you have experienced.

Can't you try to have

int maxRangeTrips=...;
range Trips=0..maxRangeTrips;

and you set maxRangeTrips thru  CustomOplDataSource
