The syntax is closer to the data step one. +1. It is a pure macro code (it can be executed in any place + of 4GL code), this includes generating macroarrays out + of datasets. +2. When a macroarrray is created it allows also to generate + a new macro (named the same as the array name) and replace + the double ampersand syntax with more array looking one, + i.e. for array ABC user can have `%ABC(1)`, `%ABC(2)`, or `%ABC(&i)` + constructions. +3. The array macro allows to use data step functions to generate + array's entries. + +The `%array()` macro executes like a pure macro code. + +### SYNTAX: ################################################################### + +The basic syntax is the following, the `<...>` means optional parameters: +~~~~~~~~~~~~~~~~~~~~~~~sas +%array( + array + <,function=> + <,before=> + <,after=> + <,vnames=N> + <,macarray=N> + <,ds=> + <,vars=> + <,q=> +) +~~~~~~~~~~~~~~~~~~~~~~~ + +**Arguments description**: + +1. `array` - *Required*, an array name and a declaration/definition of an array,

+ or `myCrr[3] $ ("d d d" "e,e,e" "f;f;f")`
+ or `myDrr p q r s`.
+ Macrovariables created by the macro are *global*. + If an array name is `_` (single underscore) then attached variables + list names are used, a call of the form: + `%array(_[*] p1 q2 r3 s4 (-1 -2 -3 -4))` + will create macrovariables: `p1`, `q2`, `r3`, and `s4` with respective + values: `-1`, `-2`, `-3`, and `-4`.
+ Three additional *global* macrovariables: + `LBOUND`, `HBOUND`, and `N` + are generated with the macroarray.

For example, if a macroarray + `myArr` has 7 values form `varName1` to `varName7` and you want + to use them as arguments in code renaming variables, say + `rename old_varName1=new_varName1 ... ;`, instead typing phrase: + `rename %do_over(myArr,phrase=%nrstr(old_%myArr(&_I_.)=new_%myArr(&_I_.)));` + you can type much easier rephrase: + `rename %do_over(myArr,rephrase=old_?=new_?);`, + and all `?` will be replaced, under the hood, by calls to the macroarray. + For easier debuging the `do_over` macro prints the rephrased string + before and after chnge. + When the `do_over` loops with multiple array, say `myArrA`, `myArrB`, + and `myArrC`, then those arrays should be refered by `?1?`, `?2?`, + and `?3?` respectively. + See `trigger` parameter definition to learn more. + If both `phrase` and `rephrase` are used, the seconf takes precedence. + +* `trigger=` - *Optional*, a single byte character (symbol) used for marking + macroarrays in the newly created phrase. + Default value is `?` symbol. + When one macroarray is used, only the symbol should be used in + `rephrase=` string. When multiple macroarrays are used then the + symbol should surroun a number identifying array, e.g. `?2?`. + See examples below for details. + +* `unq=` - *Optional*, indicates that the `%unquote()` macro function should + be added around every macroarray call. Because of SAS internal + behavior `unq=1` is needed for certain cases when plain 4GL code + is used in `rephrase=`. For example, let macro array `myArr()` + has 3 values: `A1`, `B2`, and `C3`. When the following code + is run: `%do_over(myArr, rephrase=data ?_test; run;)` without + `unq=1`, SAS will create 4 data sets: `A1`, `B2`, `C3`, + and `_test`, instead 3 data sets: `A1_test`, `B2_test`, and `C3_test`. + Default value `1` means: add the `%unquote()`. + See example below to learn more. + + +### EXAMPLES AND USECASES: #################################################### + +**EXAMPLE 1.** Simple looping. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(beta[*] j k l m (101 102 103 104), vnames=Y, macarray=Y) + + %put #%do_over(beta)#; + + %put #%do_over(beta, phrase=%nrstr("%beta(&_I_.)"), between=%str(,))#; + + data test1; + %array(beta[*] j k l m (101 102 103 104), vnames=Y, macarray=Y) + %do_over(beta, phrase=%nrstr(a&_I_. = "%beta(&_I_.)";)) + put _all_; + run; +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 2.** Multiple arrays looping. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(alpha[*] j k l m n, vnames=Y, macarray=Y) + %array( beta[5] $ , function = "a", macarray=Y) + %array(gamma[4] (101 102 103 104), macarray=Y) + + data test2; + call streaminit(123); + %do_over(beta + , phrase = %nrstr(%beta(&_I_.) = %gamma(&_I_.) * rand('Uniform'); output;) + , between = put _all_; + ); + put _all_; + run; +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 3.** Multiple arrays looping, cont. + Create multiple datasets. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %do_over(beta + , phrase = %nrstr( + data %alpha(&_I_.)2; + call streaminit(123); + %beta(&_I_.)x = %gamma(&_I_.) * rand('Uniform'); + output; + run; + ) + ) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 4.** Multiple arrays looping, cont. + Create multiple datasets using a macro. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %macro doit(ds, var=a, val=1); + data &ds.; + call streaminit(123); + &var. = &val. * rand('Uniform'); + output; + run; + %mend doit; + + %do_over(beta + , phrase = %nrstr( + %DOIT(%alpha(&_I_.)1, var = %beta(&_I_.), val = %gamma(&_I_.)) + ) + ) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 5.** `%do_over()` inside `%array()` + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(test[*] x1-x12 (1:12), macarray=Y) + + %put **%test(1)**%test(12)**; + + %put #%do_over(test)#; + + %array(abc[*] x1-x12 (%do_over(test,phrase=%nrstr(%eval(100-%test(&_I_.))))), macarray=Y) + + %put **%abc(1)**%abc(12)**; + + %put #%do_over(abc)#; +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 6.** Looping over array with *macroquoted* separator. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(alpha[11] (5:15), macarray=Y) + + %let x = %do_over(alpha + , between= %str( + ) + ); + %put &=x.; + %put %sysevalf(&x.); +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 7.** Working with the `WHICH=` optional parameter + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(test[*] x01-x12, vnames= Y, macarray=Y) + + %put #%do_over(test)#; + + %put #%do_over(test, which= 1 3 5)#; + + %put #%do_over(test, which= 1:5)#; + + %put #%do_over(test, which= 1:5:2 7 8)#; + + %put #%do_over(test, which= L:H l:h)#; + + %put #%do_over(test, which= L:3 10:h)#; + + %put #%do_over(test, which= L:H h:l:-1 13 14)#; + + %put #%do_over(test, which= %eval(1+1):%eval(5+1))#; + + %put #%do_over(test, which= L:H h:l:-1 13 14, between=%str(,))#; +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 8.** Simpler multiple arrays looping with `rephrase=`. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas + %array(alpha[*] j k l m n o p, vnames=Y, macarray=Y) + %array( beta[&alphaN.], function = (2**_i_), macarray=Y) + %array(gamma[&alphaN.] (1:&alphaN.), macarray=Y) + + %put >>%do_over(alpha)<<; + %put >>%do_over(beta)<<; + %put >>%do_over(gamma)<<; + + data test8; + call streaminit(123); + + %do_over( alpha beta gamma + , rephrase = ?1? = ?2? + ?3? * rand('Uniform'); output; + , between = put _all_; + ) + put _all_; + run; +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +**EXAMPLE 9.** Simpler multiple arrays looping with `rephrase=`, cont. + Create multiple datasets.

No longer than *10* characters. + +2. `METHOD` - *Optional*, if empty (or DECLARE or DCL) then the code of + a macro hash table is compiled. + If `DELETE` then the macro hash table named by `H` and all + macrovariables named like "`&H._`" are deleted. + +* `HASH=` - *Optional*, indicates which hashing algorithms should be used, + available values are `CRC32` or `MD5`, the `CRC32` is the default. + +--- + +### THE CREATED MACRO `%&H.()`: #################################################### + +The created macro imitates behaviour of a hash table or a dictionary. +It is *not* dedicated for "long-ish" lists (above 1000 elements) since +the performance may be poor. + +The basic syntax is the following, the `<...>` means optional parameters: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas +%&H.( + METHOD + <,KEY=> + <,DATA=> +) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +**Arguments description**: + +1. `METHOD` - *Required*, indicate what behaviour should be executed. + Allowed values are: + - `ADD`, adds key and data portion to the macro hash table, + *multiple data portions* are available for one key. + - `FIND`, tests if given key exists in the macro hash table + and, if yes, returns data value associated with the key. + For multiple data portions see the `data=` parameter. + - `DP` (data portion) or `CHECK`, returns the number of data + portions for a given key. + - `CLEAR` removes all data and keys values. + - `KEYIDX`, allows to get data by the key index rather than value. + - `KEYVAL`, returns key value for a given key index. + - `CHECKIDX`, returns the number of data portions for + a given key index. + +* `KEY=` - *Optional*, provides key value for `ADD`, `FIND`,`DP`, `CHECK` + `CHECKIDX`, `KEYIDX`, and `KEYVAL` methods. Leading and trimming + spaces are removed from the value. + The `hashing(CRC32,...)` function or the `MD5(...)` function is + used to generate the hash. + +* `DATA=` - *Optional*, provides data value for the `ADD` method and + for the`FIND` method provides data portion number to be + extracted.
