# SAS_PACKAGES
SAS Packages Repository
# SAS_PACKAGES, a SAS Packages Repository
### The User:
- Create a folder for your packages, e.g. under Windows OS family `C:/SAS_PACKAGES` or under Linux/UNIX OS family `/home/<username>/SAS_PACKAGES`.
- Copy the `loadpackage.sas` file into the packages' folder.
- Copy the `<packageName>.zip` file into the packages' folder.
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`.
- Download the `loadpackage.sas` file into the packages folder.
- Download the `<packageName>.zip` file into the packages folder.
- Execute:
```
filename packages "<directory/containing/packages/>";
%include packages(loadpackage.sas);
%loadPackage(packageName)
%helpPackage(packageName) /* to get help about package */
%loadPackage(packageName) /* to load package content */
```
### The Developer:
To create your own package:
Read the `SAS(r) packages - the way to share (a how to)- Paper 4725-2020.pdf` to learn more.
### Avaliable packages:
### Available packages:
Currently the following packages are available:
- *SQLinDS*, allows to write SQL queries in the datastep
- *DFA* (Dynamic Function Arrays), contains FCMP implementation of dynamic array, stack, fifo, ordered stack, and priority queue
- *dynMacroArray*, set of macros (wrappers for a hash table) emulating dynamic array in the datastep
- *macroArray*, implementation of an array concept in macrolanguage (e.g. `%array(ABC[17] (1:17), macarray=Y); %do i = 1 %to 17; %put %ABC(&i.); %end;`)
- **SQLinDS**, 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 datastep, e.g.
```
data class;
set %SQL(select * from sashelp.class ordered by age);
run;
```
- **DFA** (Dynamic Function Arrays), 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.
- **macroArray**, implementation of an array concept in a macrolanguage, e.g.
```
%array(ABC[17] (111:127), macarray=Y);
%do i = 1 %to 17;
%put &i.) %ABC(&i.);
%end;
%let %ABC(13,M=i) = 999;
%do i = 1 %to 17;
%put &i.) %ABC(&i.);
%end;
```
- **dynMacroArray**, set of macros (wrappers for a hash table) emulating dynamic array in the datastep (macro predecessor of DFA)
