## >>> `%createDFBitmap()` macro: <<< <a name="createdfbitmap-macro"></a> #######################
The `%createDFBitmap()` macro allows to generate
a `dynamic function bitmap` which is a FCMP based
approach to create *dynamically* allocated **numeric**
bitmnap.
*Note:* Arrays provided by the macro are *one dimensional* arrays.
The idea of a SAS bitmap is based on:

### SYNTAX: ###################################################################
The basic syntax is the following, the `<...>` means optional parameters:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
%createDFBitmap(
bitmapName
<,debug=0>
<,outlib=work.DFAfcmp.package>
<,type=32>
)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**Arguments description**:
1. `bitmapName` - *Required*, creates a FCMP call subroutine which is also
a bitmap name. In the data step it is used in form of
a call subroutine, e.g. `call bitmapName("Allocate", 3000)`.
Has to satisfy FCMP function naming requirements, but with
maximum of 24 characters.
* `debug=` - *Optional*, the default value is `0`.
If set to `1` then it turns on a debugging mode.
* `outlib=` - *Optional*, the default value is `work.DFAfcmp.package`.
It points the default location for new generated dynamic
function arrays compiled by FCMP.
*Hint!* Keep it as it is.
* `type=` - *Optional*, the default value is `32`. Sets the type of
bitwise operations executed internaly on the bitmap.
The only valid values are `32` or `52`,
With 32 the `BOR()` and `BAND()` SAS functions are used
and with 52 the `bit64orDFA()` and `bit64and DFA()` FCMP
functions are used.
**Created function arguments description**:
A function generated by the macro is:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
call &bitmapName.(IO, position, value)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
and accepts the following list of arguments and values:
1. `IO` - is a *character* steering argument, possible
values and behaviour they call are the following:
- `Check`, `Test`, `T` - to get information if a bit is set to 1 (on) or not,
- `On`, `1` - to set a selected bit to 1,
- `Off`, `0` - to set a selected bit to 0,
- `C`, `Clear` - to reduce a bitmat to a single empty cell,
- `A`, `Allocate` - to reserve space for a bitmap and set all bits to 0,
- `A0`, `Allocate0` - to reserve space for a bitmap and set all bits to 0,
- `A1`, `Allocate1` - to reserve space for a bitmap and set all bits to 1,
- `D`, `Dim`, `Dimension` - to returns minimal and maximal index of the bitmap.
2. `position` - is a *numeric* argument and depends on the `IO` value.
Behaves in the following way:
- for `On`, `Off`, `1`, `0`/ `Check`, `Test`, `T` it is a bitmap index,
- for `C`, `Clear` is ignored,
- for `A`, `Allocate` sets the value of the minposition, i.e. the minimal position of the bitmap index,
- for `D`, `Dimension` it returns value of the minposition,
.3 `value` - is a *numeric* argument and depends on the `IO` value.
Behaves in the following way:
- for `Check`, `Test`, `T` it holds value retrieved from a bitmap on a given position,
- for `On`, `Off`, `1`, `0`, `C`, `Clear` is ignored,
- for `A`, `Allocate` it sets the value of the maxposition, i.e. maximal position of the array index,
- for `D`, `Dimension` it returns value of the maxposition
The `position` and the `value` arguments are **outargs**, i.e. can be changed by the function.
