I was not sure about the use of a structure in the READS call,
but the following example illustrates my point more completely.

IDL> s='12, 24  36 3.456  2 3 4 5, 6,7'

;                 ^ there is a tab in this string here

IDL> a={f1:0, f2:0, f3:0L, f4:0., f5:intarr(6)}

IDL> help,/str,a
** Structure <4009be08>, 5 tags, length=24, refs=1:
   F1              INT              0
   F2              INT              0
   F3              LONG                 0
   F4              FLOAT           0.00000
   F5              INT       Array(6)

IDL> reads,s,a

IDL> help,/str,a
** Structure <4009be08>, 5 tags, length=24, refs=1:
   F1              INT             12
   F2              INT             24
   F3              LONG                36
   F4              FLOAT           3.45600
   F5              INT       Array(6)
IDL> print,a.f5
       2       3       4       5       6       7

	Have fun,
