I expect you will run into other limits before you get to 45,000 
variables, but if you keep reusing the same name in the infile statement
or dictionary, I expect that will avoid the limit on the number of 
variables itself:

  infile dummy dummy dummy var1 var2 dummy dummy

may only be 3 variables from Stata's point of view, but I haven't actually 
tried to read more than 32767, of course.
