string can be used like sprintf in C
You have to create the Format specification on the fly

IDL> string_array=['one ','string ','split ',$
'into ','many ','array elements']
IDL> help,string_array & print,string_array
STRING_ARRAY STRING = Array[6]
one string split into many array elements
IDL> one_string = string(string_array, $
format = '(' + string(n_elements(string_array)) + 'A)')

IDL> help,one_string & print,one_string
ONE_STRING STRING = 'one string split into many array elements'
one string split into many array elements
