A SAS package is an automatically generated, single, stand alone zip file containing organised and ordered code structures, created by the developer and extended with additional automatically generated "driving" files (i.e. description, metadata, load, unload, and help files).
The purpose of a package is to be a simple, and easy to access, code sharing medium, which will allow: on the one hand, to separate the code complex dependencies created by the developer from the user experience with the final product and, on the other hand, reduce developer's and user's unnecessary frustration related to a remote deployment process.
In this repository we are presenting the SAS Packages Framework which allows to develop and use SAS packages. The latest version of SPF is 20220420
.
To get started with SAS Packages try this Getting Started with SAS Packages
presentation (see the ./SPF/Documentation
directory).
The documentation and more advance reading would be the SAS(r) packages - the way to share (a how to)- Paper 4725-2020 - extended.pdf
article (see the ./SPF/Documentation
directory).
Short description of the SAS Packages Framework macros can be found here

A SASware Ballot Idea for adding SAS Packages Framework macros into Base SAS and Viya was submitted Friday, May 27th 2022. If you would like to support the idea visit this communities.sas.com post and up vote the idea!
To use a package:
- Create a folder for your packages, under Windows OS family, e.g.
C:/SAS_PACKAGES
or under Linux/UNIX OS family, e.g./home/<username>/SAS_PACKAGES
.
and then either:
- Download the
SPFinit.sas
file (the SAS Packages Framework) into the local packages folder. - [Optional] Manually download the
<packageName>.zip
file into the local packages folder. - and Execute:
filename packages "<directory/containing/packages/>"; /* setup directory for packages */
%include packages(SPFinit.sas); /* enable the framework */
/* %installPackage(packageName) */ /* install the package, unless you downloaded it manually */
%helpPackage(packageName) /* get help about the package */
%loadPackage(packageName) /* load the package content into the SAS session */
or if you need it just for "one time" only Execute:
filename packages "%sysfunc(pathname(work))"; /* setup temporary directory for packages in the WORK */
filename SPFinit url "https://raw.githubusercontent.com/yabwon/SAS_PACKAGES/main/SPF/SPFinit.sas";
%include SPFinit; /* enable the framework */
%installPackage(packageName) /* install the package */
%helpPackage(packageName) /* get help about the package */
%loadPackage(packageName) /* load the package content into the SAS session */
Workshop video for the User [May 6th, 2020] [a bit outdated but gives the idea how it works]
To create your own package:
- Read the
SAS Packages - The Way to Share (a How-To) - Paper 4725-2020 - extended version
article to learn more details. - Read the
My First SAS Package: A How-To - Paper 1079-2021
article available at communities.sas.comhere
or locallyhere
- Download and use the
SPFinit.sas
file (the SAS Packages Framework), the part of the framework required for testing is there too.
Update[November 11th, 2021]: %extendPackagesFileref()
macro is available.
Update[October 15th, 2020]: %previewPackage()
macro is available.
Update[September 11th, 2020]: %loadPackageS()
and %verifyPackage()
macros are available.
Update[July 30th, 2020]: All components of SAS Packages Framework are now in one file SPFinit.sas
(located in the ./SPF
directory). Documentation moved to ./SPF/Documentation
directory. Packages zip files moved to ./packages
directory.
Update[June 10th, 2020]: To see help info about framework macros and their parameters just run: %generatePackage()
, %installPackage()
, %helpPackage()
, %loadPackage()
, and %unloadPackage()
with empty parameter list.
Update[June 3rd, 2020]: %installPackage()
macro is available. The %installPackage()
macro is embedded in the loadpackage.sas
part of the framework.
This is a list of locations where the SAS Packages Framework is used:
- Warsaw (Poland)
If you want to share that you are using the SPF let me know and I'll update the list.
If you find the SPF useful share info about it or give it a star so more people will know.
Currently the following packages are available (see the ./packages
directory):
- SQLinDS[2.2], based on Mike Rhoads' article Use the Full Power of SAS in Your Function-Style Macros. The package allows to write SQL queries in the data step, e.g.
data class;
set %SQL(select * from sashelp.class order by age);
run;
SHA256 digest for SQLinDS: 701B69BE71B99792803BCE7718ED486259310FFB92E6D77ED1BC029D9CC67B60
- MacroCore[1], a macro library for SAS application developers. Over 100 macros for Base SAS, metadata, and Viya. Provided by the SASjs framework.
SHA256 digest for MacroCore: A23C29529F3CE7D0C8BEE9545C5D22D5B5594907547374A5135B8E5A48D7687B
- DFA (Dynamic Function Arrays)[0.5], contains set of macros and FCMP functions which implement: a dynamically allocated array, a stack, a fifo queue, an ordered stack, and a priority queue, run
%helpPackage(DFA,createDFArray)
to find examples.
SHA256 digest for DFA: 6B3FB0B06B47A7EF1BB004B483B0F39B8F553F7F16D02A7E24CDE388BBA704EA
- macroArray[1.0], implementation of an array concept in a macrolanguage, e.g.
%array(ABC[17] (111:127), macarray=Y);
%macro test();
%do i = 1 %to 17;
%put &i.) %ABC(&i.);
%end;
%mend;
%test()
%let %ABC(13,i) = 99999; /* i = insert */
%do_over(ABC, phrase=%nrstr(
%put &_i_.%) %ABC(&_i_.);
),
which = 1:H:2
);

- BasePlus[1.17] adds a bunch of functionalities I am missing in BASE SAS, such as:
call arrMissToRight(myArray);
call arrFillMiss(17, myArray);
call arrFill(42, myArray);
rc = delDataset("DataSetToDrop");
string = catXFn("date9.", "#", myArray);
format x bool.;
%put %getVars(sashelp.class, pattern = ght$, sep = +, varRange = _numeric_);
%rainCloudPlot(sashelp.cars,DriveTrain,Invoice)
%zipLibrary(sashelp,libOut=work)

- GSM (Generate Secure Macros)[0.20], package allows to create secured macros stored in SAS Proc FCMP functions. The dataset with functions can be shared between different operating systems and allows to generate macros on site without showing their code.
SHA256 digest for GSM: E6E2A6214EE7DC6E06AA76916A68B216DD7665184E63CF2C01F487A038E71B09
- dynMacroArray[0.2], set of macros (wrappers for a hash table) emulating dynamic array in the data step (macro predecessor of DFA)
