Thanks for your help and sorry for the ambiguity in my explanation.
I was able to construct a foreach command that generates the same
results as your suggestions.
But the results from tabstat are displayed like the following;
variable | mean N max min p50
-------------+--------------------------------------------------
telephone | 1.960888 2659 2 1 2
----------------------------------------------------------------
variable | mean N max min p50
-------------+--------------------------------------------------
telephoneno | 1.25 104 5 1 1
----------------------------------------------------------------
variable | mean N max min p50
-------------+--------------------------------------------------
telephonesh | 1.929293 99 2 1 2
----------------------------------------------------------------
variable | mean N max min p50
-------------+--------------------------------------------------
telephones~o | 4.428571 7 20 1 2
----------------------------------------------------------------
But what I wanted to do was actually producing following results by loop;
variable | mean N max min p50
-------------+--------------------------------------------------
telephone | 1.960888 2659 2 1 2
telephoneno | 1.25 104 5 1 1
telephonesh | 1.929293 99 2 1 2
telephones~o | 4.428571 7 20 1 2
----------------------------------------------------------------
variable | mean N max min p50
-------------+--------------------------------------------------
clock | 1.285446 2659 2 1 1
clockno | 1.996839 1898 15 1 2
----------------------------------------------------------------
i.e. displaying the results from tabstat by the set of variables that
shares the same prefix.
Of course, the above examples were achieved by writing a single
command line for each group.
But as I have many such variables, I would somehow want to do this
with foreach command(s).
