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,
