Sorry, that part is incorrect. While this works with selecting some variables using the -use- command, it doesn't work for -insheet- in the same way--I got these two confused. (The varlist in -insheet- expects you to specify the names of all the variables, not a subset to be loaded)

I'd like to load a very large ASCII .csv file into a .dta Stata file but it keeps bumping up against the 1.1g memory limit and Stata suggests I "drop some observations or variables." My question is how one can load just a portion of an ASCII file--for example, the specific variables of interest, or only those observations where variable1=xyz--so as to end up with a more manageable Stata file.
