I am interested to write 6*6*4 array in opl cplex.

I have declared like this

Int cmf [route][nodes][nodes] = …;

How to write the data file?

Nodes = 1..6;

Nodes = 1..6;

While route = 4;

I have declared like 

cmf = [[[[  [0 1 2 1 2 3]
 [1 0 1 1 2 2]
  [2 1 0 2 1 1]
  [1 1 2 0 1 2]
  [2 2 1 1 0 1]
  [3 2 1 2 1 0]]
 
  [ [0 2 3 2 3 4]
  [2 0 3 3 3 3]
  [3 3 0 3 3 2]
  [2 2 3 0 2 3]
  [3 3 3 3 0 2]
  [4 3 2 3 2 0]]] 
  
  [ [0 4 4 4 4 5]
  [4 0 4 4 3 4]
  [4 4 0 3 3 4]
  [4 3 3 0 4 4]
  [4 3 3 4 0 4]
  [4 4 4 4 4 0]]]
 
  [  [0 5 4 5 4 5]
 [5 0 5 5 3 4]
  [4 5 0 3 4 5]
  [5 4 3 0 5 4]
  [4 3 4 4 0 5]
  [5 4 5 4 5 0]] ];

but it give me an error of data array unexpected  for int. Kindly help me. your help will be highly appricated. thank you

Your array has too many dimensions. You need to define only three dimensions (i.e. only three opening square brackets in the beginning). Something like

cmf = [ [ [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6] ],
        [ [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6] ],
        [ [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6] ],
        [ [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6], [ 1, 2, 3, 4, 5, 6] ] ];
