The STRING function can be used to get the same lines of text that IDL
prints with PRINT:
IDL> a=bindgen(3,2,3,2)
IDL> print,a
0 1 2
3 4 5
6 7 8
9 10 11
12 13 14
15 16 17
18 19 20
21 22 23
24 25 26
27 28 29
30 31 32
33 34 35
IDL> s=string(a,/print)
IDL> help,s
S STRING = Array[17]
IDL> print,s,format='(A)' ; To see each on its own line
0 1 2
3 4 5
6 7 8
9 10 11
12 13 14
15 16 17
18 19 20
21 22 23
24 25 26
27 28 29
30 31 32
33 34 35
Some further trickery based on the dimensions of the array could be used to
stuff indicators in the right places (like: "a[*,*,0,0]" before the first 2D
section) if that's what you meant by "add an index before".
Hope this helps.
Cheers,
