You do not need to type all the variable names by hand. Try something like this
u <shorter_file> ,clear
unab vars : *
loc vars `vars' <varnames_to_add>
ap using <longer_file> ,keep(`vars')
where, obviously, you do not type the < and >, and replace the content
inside with whatever filenames, and variable names you have.

Hi all,
I have two files, one (A) with 2045 variables while another (B) has
1055 variables. I wanted to append to A using B.
However since there are some variables in B which are not in A, I end
up with more than the allowable 2048 variables for my version of STATA
(STATA 12)
I have to use the option "keep" and list what I want from B. This for
sure is too long a command.
I
only wanted to append to those variables already in A from B and maybe
add two new variables, thus remaining with either 2045 or with 2047 variables.
I am
using data from a cohort of individuals we have been following for over
10 years with many variables standing for questions asked at each
survey round (64 page
questionnaire).
Is there a command I can use to only append to
those variables that are already in my working file (A) and maybe also "keep"
only two more variables?
Thank you
