arrange row to column

[RC13]

Assume the below text file;
*****************
freq S11
1 11
2 22
3 33

freq S21
1 111
2 222
3 333
*****************
I need to make it to;
*****************
freq S11 S22
1 11 111
2 22 222
3 33 333
*****************

I have more than 100 of this files to process.
I wonder awk can do this?
Thanks.

Indeed...
[tt]awk '/./ {a[$1]=a[$1] $2 &quot; &quot;} END {for(n in a) print n, a[n]}' <file |sort -n[/tt]
Gives...
[tt]freq S11 S21
1 11 111
2 22 222
3 33 333[/tt]
