macroArray, version 0.7:

The `%mcHashTable()` macro was added in the package.
It is designed to facilitate the idea of a "macro hash table"
concept, i.e. *a list of macrovariables with common prefix
and suffixes generated as a hash digest* which allows
to use values other than integers as indexes.
The `%mcHashTable()` macro allows to generate other macros
which behaves like hash tables or dictionaries.

## SAS Packages:
To get started with SAS Packages try this [**`Getting Started with SAS Packages`**](https://github.com/yabwon/SAS_PACKAGES/blob/master/SPF/Documentation/Getting_Started_with_SAS_Packages.pdf "Getting Started with SAS Packages") presentation (see the `./SPF/Documentation` directory).
## 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;
run;
```
SHA256 digest for SQLinDS: 135DC50C0412B8CEAF6D5349B8A203C0ADB23D4F5C2680B6A35FD2E5482B6C49

- **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);
end;
L = .; H = .;
call ArrDynamic("Dim", L, H);
put L= H=;
call ArrDynamic("+", 3, 8);
call ArrDynamic("+",-3, 0.125);
call ArrDynamic("Dim", L, H);
put L= H=;
Value = .;
do i = L to H;
call ArrDynamic("O", i, Value);
put i= Value=;
end;
run;
```
SHA256 digest for DFA: E67A0863992722A5F535F56E14EF8D19A55F74FB374447BF11B5ED74029C29CB
---
- **macroArray**\[0.7\], 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;
%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**\[0.8\] 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_);
```

- **dynMacroArray**\[0.2\], set of macros (wrappers for a hash table) emulating dynamic array in the data step (macro predecessor of DFA)
SHA256 digest for dynMacroArray: 694AACE925B7F4E149C3B90383F56370ED76233D8F5040713D66C1F3A4E414FE
