<> " I strongly suggest you set varabbrev off which will cause most of Martin's sample code to fail, but will make life simpler in a number of instances." Kit, which sample code are you referring to? Mine (http://www.stata.com/statalist/archive/2010-02/msg01122.html) works perfectly with -varabbrev- off: ************* clear* set mem 500m set obs 13700 set matsize 10000 set varabbrev off foreach var of newlist var1-var2500{ gen byte `var'=runiform()<.3 } gen y=rnormal() reg y var1-var2500 ************* BTW, I consider -g- as an abbreviation for -generate- much worse than abbreviations for variables, but that`s just me...

Februar 2010 17:06 An: statalist@hsphsun2.harvard.edu Betreff: re: st: RE: regression r(103): too many variables <> Paul said in most other stats programs I've worked with, a single hyphen in a list of this type (i.e., dum_1_int_1-dum_1_int_96) would be expanded out in logical sequential fashion (i.e., dum_1_int_1 dum_1_int_2 ...). But Stata expanded it out in the physical order in which the variables appeared in the data set but in Stataland, a hyphenated varlist (help varlist) ALWAYS obeys the order (help order) of the dataset, and has nothing to do with the names of the variables encompassed by that range. You can induce the behavior you want by using -order-, but it is probably safer to use wildcards -- and perhaps even the more restrictive form of wildcards with ? rather than *. Another pet peeve of mine involves automatic variable abbreviations. I strongly suggest you set varabbrev off which will cause most of Martin's sample code to fail, but will make life simpler in a number of instances.
