I am wondering if there's a straightforward way to append a large
number of .dta files into one file..
If you have Stat/Transfer this is trivial:
combine *.dta big.dta
A very nice thing about this command is that it will match up the
variables if necessary. You can also specify a "reference" input
file that contains all of your variables in the order you
want. Optionally, the file names can be made into an additional
variable in the output file. The combine command will work for any
input or output file type supported by Stat/Transfer.
Best,
Steve
