# A SAS User's Guide to Stata

This guide is intended to introduce a SAS user to Stata and to be a cheat sheet when writing Stata code.

- Basic Conceptual Differences Between
**SAS**and**Stata**. - Stata's Windows Mode
**SAS**code matched to**Stata**code**SAS**functions matched to**Stata**functions- How to submit
**Stata**do-files in batch mode

### Tools to transfer data between SAS and Stata

(all require that both SAS and Stata are able to be invoked on the same computer)

- SAVASTATA: SAS macro to save a SAS dataset as a Stata dataset.
- SAVASAS: Stata command to save a Stata dataset as a SAS dataset.
- USESAS: Stata command to use a SAS dataset while in Stata.
- USESTATA: See the example in the STATA WRAPPER page that shows you how to create a SAS dataset from a Stata dataset.
- SAVAS (c-shell) script: Invoked at a UNIX/Linux prompt makes Stata datafile copies of SAS datafiles or SAS datafile copies of Stata datafiles.
- STATA_WRAPPER: SAS macro to run Stata code from within SAS.
- SASWRAPPER: Stata command to run a SAS program from within Stata.

### SAS macros inspired by Stata programs

- CHAR2FMT: SAS macro to encode character variables.
- RUNQUIT: SAS macro to stop SAS from processing more code when an error occurs without ending your SAS session.
- ISID: SAS macro to test if variable(s) uniquely identify each observation in a dataset.
- MINIME: SAS macro to reset variable lengths to minimize the SAS dataset.
- WHICH: Find out what SAS macro SAS will invoke.
- REN_STEM: SAS macro to rename variables.
- TYPE: SAS macro to print a text file to your SAS output window.

### Stata programs

- ADOEDIT: Stata command to edit an ado-file in Stata's do-file editor
- ETIME: Stata command to keep track of elapsed time
- IFWINS: Stata command to subset dataset by if exp before subsetting by in range
- LOOKFORIT: Stata command to search variable names and variable labels for some string or strings
- LOOKFOR_ALL: Searches for variables/patterns in Stata data files (.dta)
- LSTRFUN: Modify long local macros that contain strings
- MKPROFILE: Stata command to create or edit your profile.do
- NSPLIT: Stata command to split numeric variables with integer values into new smaller numeric variables
- RCD: Recursively traverse directories and execute any command in or for each one of them

### Tools to transfer data between SAS matrix catalog files and SAS datasets

These SAS macros use **PROC IML** and are a great way to migrate a SAS matrix catalog file between operating systems since SAS catalog files can only be opened in the operating system they were created on.

- MAT2DAT: SAS macro to create SAS datasets from a SAS matrix catalog file
- DAT2MAT: SAS macro to create a SAS matrix catalog file from SAS datasets
