Too many keep statements: was: Re: st: Date: Sun, 8 Sep 2013 23:54:39 +0000

You might take advantage of consecutively numbered
choices with the inrange() function:


.keep if inrange(typex,1,16) |
         inrange(typex,21,30)


Next time, follow the Statalist FAQ and give your post an informative title.

-encode- your string variable to a corresponding numeric variable, typex, with the
original names as value labels. 


To save typing continuation comments "///", temporarily set the statement delimiter to ";"

#delim ;

keep if 
inlist(typex,

1,2,3,4,5,6,7,8,10
11,12,13,14,15,16
/* etc. */
);

#delim cr

Would it be easier to use -drop if-? -drop if- could also be split into multiple commands if necessary.
