Thank you for your suggestion.
I haven't known of such a covenient command.
I think the richness of this kind of commands for data
management is one of the advanteges of using Stata.

Oh, I haven't checked this issue yet!
Thank you for your reminder.

Sorry. "Stat Transfer". is correct.
And the sentence that 'string variables can't
be used with -rename-' is surely incorrect.
But, I'm afraid these string variables can't be used with
-generate- or -rename- or -forvalues-, as far as my data
is concerned.
The relevant part of the data is as follows:
-----------------------------------
storage display
variable name type format
-----------------------------------
_1 int %8.0g
_2 int %8.0g
_3 int %8.0g
_4 int %8.0g
_5 int %8.0g
_6 int %8.0g
_7 int %8.0g
_8 int %8.0g
_9 int %8.0g
_10 int %8.0g
_11 str15 %15s
....
Given this structure, when typed 'gen SQ11 = _11', or
'forvalues i = 1/11 {gen SQ`i' = _`i'}', Stata says,
'type mismatch r(109);'
Maybe I did somehing wrong, but I don't know what the
cause is.
K.I.
