SAS Packages Framework, version 20201001

SAS Packages Framework, version 20201001
- `%installPackage` macro allows to install/download the framework file like any other package, e.g. `%installPackage(SPFinit)`,
- improvement in testing if HASHING_FILE function is available,
- documentation updated.

 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.

-- Read the **`SAS(r) packages - the way to share (a how to)- Paper 4725-2020 - extended.pdf`** to learn more.
-- Download and use the `generatePackage.sas` file (developer part of the framework) and the `loadpackage.sas` file (user part of the framework but required for *testing*).

+
+## Available packages: 
+Currently the following packages are available:
+
+- **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 age, name, weight, height 
+    from sashelp.class 
+    order by age
+    );
+    
+    WH = weight + height;

+
+[Documentation for SQLinDS](https://github.com/yabwon/SAS_PACKAGES/blob/master/packages/sqlinds.md "Documentation for SQLinDS")
+
+
+- **DFA** (Dynamic Function Arrays)\[0.2\], 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.
+```
+%createDFArray(ArrDynamic, resizefactor=17); 
+
+data _null_;
+  call ArrDynamic("Allocate", -2, 2);
+
+  do i = -2 to 2;
+    call ArrDynamic("Input", i, 2**i);

+
+
+- **macroArray**\[0.5\], implementation of an array concept in a macro language, e.g. 
+```
+  %array(ABC[17] (111:127), macarray=Y); 
+  
+  %macro test();
+    %do i = 1 %to 17;

+[Documentation for macroArray](https://github.com/yabwon/SAS_PACKAGES/blob/master/packages/macroarray.md "Documentation for macroArray")
+
+- **BasePlus**\[0.62\] adds a bunch of functionalities I am missing in BASE SAS, such as: 
+```
+call arrMissToRight(myArray);

+# The SQLinDS package [ver. 2.2] <a name="sqlinds-package"></a> ###############################################
+
+The **SQLinDS** package is an implementation of 
+the *macro-function-sandwich* concept introduced in the 
+*"Use the Full Power of SAS in Your Function-Style Macros"*,
+the article by *Mike Rhoads (Westat, Rockville)*.
+
+Copy of the article is available at:
+[https://support.sas.com/resources/papers/proceedings12/004-2012.pdf](https://support.sas.com/resources/papers/proceedings12/004-2012.pdf)
+
+Package provides ability to *execute* SQL queries inside a data step, e.g.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+  data class;
+    set %SQL(select * from sashelp.class);
+  run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See the help for the `%SQL()` macro to find more examples. 
+
+### Content ###################################################################
+
+SQLinDS package contains the following components:
+
+1. `%SQL()` macro - the main package macro available for the User
+2. `dsSQL()` function (internal)
+3. `%dsSQL_inner()` macro (internal) 
+4. Library `DSSQL` (created as a subdirectory of the `WORK` library)
+
+---
+
+Package contains: 
+1.   libname    dssql 
+2.   macro      dssql_inner 
+3.   macro      sql 
+4.   function   dssql 
+
+Required SAS Components: 
+  *Base SAS Software*
+
+*SAS package generated by generatePackage, version 20200911*

+
+## >>> library `dsSQL`: <<< <a name="library-dssql"></a> ########################
+
+The `dsSQL` library stores temporary views 
+generated during the `%SQL()` macro execution.
+
+If possible a subdirectory of the `WORK` location is created, like: 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))/dsSQLtmp";
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+if not possible, then redirects to the `WORK` location, like:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+LIBNAME dsSQL BASE "%sysfunc(pathname(WORK))"; 
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+---
+
+
+
+## >>> `%dsSQL_Inner()` macro: <<< <a name="dssql-inner-macro"></a> #############
+
+**Internal** macro called by `dsSQL()` function.
+The macro generates a uniquely named SQL view on the fly
+which is then stored in the `dsSQL` library.
+
+Recommended for *SAS 9.3* and higher. 
+
+---
+
+
+
+## >>> `%SQL()` macro: <<< <a name="dssql-macro"></a> ###########################
+
+The **main** macro which allows to use 
+SQL queries in the data step.
+
+Recommended for *SAS 9.3* and higher.
+
+Based on the article *"Use the Full Power of SAS in Your Function-Style Macros"*
+by *Mike Rhoads* (Westat, Rockville), available at:
+[https://support.sas.com/resources/papers/proceedings12/004-2012.pdf](https://support.sas.com/resources/papers/proceedings12/004-2012.pdf)
+
+### SYNTAX: ###################################################################
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%sql(<nonempty sql querry code>)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The sql query code is limited to *32000* bytes.
+
+### EXAMPLES: #################################################################
+
+**EXAMPLE 1**: simple SQL query
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+data class_subset;
+  set %SQL(select name, sex, height from sashelp.class where age > 12);
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**EXAMPLE 2**: query with dataset options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+data renamed;
+  set %SQL(select * from sashelp.class where sex = "F")(rename = (age=age2));
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**EXAMPLE 3**: dictionaries in the data step
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+data dictionary;
+  set %SQL(select * from dictionary.macros);
+run;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+---
+
+
+ 
+## >>> `dsSQL()` function: <<< <a name="dssql-function"></a> ####################
+
+**Internal** function called by the `%SQL()` macro.
+The function pass a query code from the `%SQL()`
+macro to the `%dsSQL_Inner()` internal macro.
+
+Recommended for *SAS 9.3* and higher. 
+
+### SYNTAX: ###################################################################
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+dsSQL(unique_index_2, query)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `unique_index_2` - *Numeric*, internal variable, a unique index for views.
+
+2. `query` -          *Character*, internal variable, contains query text.
