Thanks to Kit Baum, a new package -outfixt- is available from SSC by typing
ssc install outfixt
-outfixt- writes variables to a text file in fixed format, at specific
column numbers. -outfixt- is a modification of -outfix2- (by Nick Cox)
which takes ideas from a program -outfix- (by Gero Lipsmeier), both of
which are also on SSC.
