I guess Julio better specify how he wants his array
concatenated. I just took him at his word. :-)

Try array3 = [[array1],[array2]]

IDL> x1=strarr(15,4)
IDL> x2=strarr(15,6)
IDL> help, x1, x2
X1 STRING = Array[15, 4]
X2 STRING = Array[15, 6]
IDL> help, [[x1],[x2]]
<Expression> STRING = Array[15, 10]

Try

Array3 = [[array1], [array2]]

and have a look at http://www.dfanning.com/tips/array_concatenation.html.

Good luck,

Array4 = StrArr(15,6)
array4[0,0] = array1
array3 = [array4, array2]
