Stata Technical Bulletin

I wrote mergedct.ado to avoid these steps. mergedct is just like Stata’s merge command except mergedct combines
the current data set with a raw or dictionary file rather than a .dta-file. The syntax for mergedct is

mergedct VyrrSsst∖ using filename [, automatic byvariable(#)

nolabel u2(aien2me2^) vlist (yrrlisf) ]

Options

mergedct combines the options of infile and merge. The automatic, byvariable(#), and u2(filrname2) options
have the same effect as the infile options automatic, byvariable(#), and usingnrien2me2), respectively. The nolabel
option has the same effect as the merge command’s nolabel option.

The vlist Varl-Isst) option is new. It is used to identify the variables when merging raw (non-dictionary) data files. The
command

. mergedct using rawdata, vlist(x y z)

indicates that the raw data can be read using the following infile command:

. infile x y z using rawdata

Examples

Here’s an example of merging a dictionary file. Note that mergedct does not require the disk data set to be sorted in
advance.
