Abstract. A text file filter is a program that converts one text file into another on
the basis of a set of rules. For statistical applications, a text file
filter can convert data embedded in a complicated text file so that Stata
can read and analyze it. A text file filter can also automate the
production of more user-friendly output from long Stata log files. The
file command lets you use text file filters in Stata. This article
reviews some key programming points for successful implementation of such
filters.
