st: generated file with append command has more than allowable number of variables

[Tom Lutalo <tomlutalo@yahoo.com>]

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

Tom
