Notes
  1. For Stata/MP, the maximum number of observations is 1,099,511,627,775, and for Stata/SE, the maximum number is 2,147,483,619. In practice, both flavors are limited by memory.
  2. The maximum length of the contents of a macro are fixed in Stata/IC and settable in Stata/SE and Stata/MP. The currently set maximum length is recorded in c(macrolen); type display c(macrolen). The maximum length can be changed with set maxvar. If you set maxvar to a larger value, the maximum length increases; if you set maxvar to a smaller value, the maximum length decreases. The relationship between them is maximum_length = 129*maxvar + 200.
  3. In Mata, matrices are limited only by the amount of memory on your computer.
