Processing Multiple Items with the For Command. You'll often want to write batch files that process 'all' of a certain type of file. Command-line programs can deal with filename wildcards: For example, you can type delete *.dat to delete all files whose name ends with.dat.In batch files, you can accomplish this sort of thing with the for loop. Removing spaces from a variable in batch. Ask Question 9. There is something wrong with your second line. There is no space between set and local in setlocal. The second line should be SETLOCAL EnableDelayedExpansion. Browse other questions tagged variables batch-file spaces or ask your own question. 5 years, 9 months ago.
If you do not see the menu on the left The Do-file IMPORTANT: Try not to copy and paste the programs, write them yourself. Two reasons: learning experience and pasting programs may not work properly (lots of issues with quotation marks) Do-files are ASCII files containing a series of Stata commands (which could include programs).
These type of files are just plain-text with the extension.do. You can use notepad, wordpad or any word processor to write do-files.
You can also use the built-in do-file editor in Stata. You can also type in the command window. Display 'Hello, world' exit NOTE: YOU MAY HAVE TO RETYPE THE SINGLE AND DOUBLE QUOTES WHEN COPYING THE DO-FILES CODES INTO STATA Go to File-Save and save it as hello.do (use whatever name you want just make sure to save it with extension.do ). IMPORTANT 1: Remember to change the path to your working directory: cd “h: statadata ”, save the do-file there. IMPORTANT 2: If you copy and paste the code be careful with quotations, you may have to retype them into Stata otherwise they program or do-file may not run Once saved, go back to the command window type.
Capture program drop hello program hello display 'Hello, world' end hello exit NOTE: YOU MAY HAVE TO RETYPE THE SINGLE AND DOUBLE QUOTES WHEN COPYING THE DO-FILES CODES INTO STATA Notice the new command capture, if there is no program called hello the do-file will not run, capture will ignore the error and let the whole program run (use this feature only when error are an annoyance in testing programs). For more details on this type help capture. Some of the examples from the previous sections to write a do-file that does the following:. Starts a log (to keep track of your work). Reads data. Describes data.
Save data. Close the log Go to the do-file editor and type DO-FILE: read1.do. IMPORTANT: Remember to specify the path or to change the working directory when running do-files or any command that refers to a particular directory (like use ), otherwise you will get the error message file not found.
You can see the output (use notepad, wordpad or word) by looking at file.log in the directory 'H: statadata ” With do-file read3.do we did the following:. Created a log for each file. Read the file. Added some variable names (optional). Described the data.
Got some summaries (if you need percentiles write summarize, detail ). Got a codebook for the dataset. Save it in Stata format As an exercise do the same thing using infile from a previous section. This works is the macro `1’ which Stata interprets as an argument. To understand it better let’s do a math exercise by creating a do-file that converts Fahrenheit into Celsius and vice versa. Go to the do-file editor in Stata and enter the following commands.

DO-FILE: convert.do.
Local variables in functions can be used to avoid name conflicts and keep variable changes local to the function. The SETLOCAL command is first used to ensure the command processor takes a backup of all environment variables. The variables can be restored by calling ENDLOCAL command.
Changes made in between are local to the current batch script. ENDLOCAL is automatically called when the end of the batch file is reached, i.e. By calling GOTO:EOF.
Localizing variables with SETLOCAL allows using variable names within a function freely without worrying about name conflicts with variables used outside the function. Following example shows how local variables can be used in functions. Example @echo off set str = Outer echo%str% CALL:SetValue str echo%str% EXIT /B%ERRORLEVEL%:SetValue SETLOCAL set str = Inner set '%1 =%str%' ENDLOCAL EXIT /B 0 Output In the above program, the variable ‘str’ is being localized in the function SetValue. Thus even though the str value is being returned back to the main function, the value of str in the main function will not be replaced by the value being returned from the function. The above command produces the following output.
