The SIZE() function returns this information. For example,

IDL> SZ = SIZE(ARRAY)
IDL> PRINT, SZ
2 50 50 4 2500

The first element gives the total number of dimensions (zero for scalars).
Following this are the dimensions, 50x50 in this example. Then there is a code
specifying what the data type is--see the manual for details. The last number
gives the total number of elements in the array.
