You have to check the format of your files. Suppose they are separated by 
comma and the first line contains the name of the variables

forvalues i=1993/2003 {
    insheet using c:\`i'.txt, comma name
    gen year = `i'
    save c:\`i', replace
    clear
}

I just cannot find the old thread about this.
I have some files called 1993.txt ... 2003.txt.

1. I want to insheet the files by "foreach" or "forvalues".
If I do:
forvalues i of 1993(1)2003 {
insheet using c:\`i'.txt
..
}
It is not working. I also tried other ways and cannot figure how. Invalid
syntax.

2. within each file processing, I need to do "gen year=`i'"

3. after the processing, I need to save the file as ...\`i'.dta.

I am obviously stuck at the "insheet" step but maybe I need to change 2 and
3 also? I appreciate your help. Thanks.

Wanli
