Text Editor[edit | edit source]
- Stata 11 includes a do-file editor with syntax highlighting.

Memory[edit | edit source]
Stata loads the data in memory. If you are dealing with large datasets, you may have the following error message : no room for more observations . In that case, you just need to increase the amount of memory used by Stata. The maximum depends on your computer.
. set mem 100m * gives 100 megabyte . set mem 1g * gives 1 gigabyte
In Stata 12, these commands are not necessary because memory is managed automatically. Stata will inform you of this change any time you run the set mem command, using this message:
set memory ignored. Memory no longer needs to be set in modern Statas; memory adjustments are performed on the fly automatically.
If you want to know more, just type mem
. mem Total memory: 105M Memory in use: 6k 0% Room for 867k more observations Room for 570k more variables (4 byte)
Profile.do[edit | edit source]
- profile.do is executed each time you open Stata. It is a simple do-file which should be located in the same directory as the .exe (Windows) or .app (Mac OS) file. You can define your ado files directory and store them in profile.do
*! profile.do sysdir set PERSONAL "/Applications/Stata/ado/personal/" sysdir set PLUS "/Applications/Stata/ado/plus/" sysdir set OLDPLACE "/Applications/Stata/ado/oldplace/" set mem 100m set more on, permanently
