### #define BOOST_PP_REPEAT(COUNT,MACRO,DATA)

Repeats the macro `MACRO(INDEX,DATA)` for `INDEX = [0,COUNT)`.

In other words, expands to the sequence:

    MACRO(0,DATA) MACRO(1,DATA) ... MACRO(BOOST_PP_DEC(COUNT),DATA)

For example,

    #define TEST(INDEX,DATA) DATA(INDEX);
    BOOST_PP_REPEAT(3,TEST,X)

expands to:

    X(0); X(1); X(2);

### 2D and 3D repetition

BOOST_PP_REPEAT() implements automatic recursion. 2D and 3D repetition are directly supported.

### Example

- duffs_device.c
- repeat_2d.c

### See

- BOOST_PP_FOR()
- BOOST_PP_LIMIT_DIM
- BOOST_PP_LIMIT_MAG

### Test

- repeat_test.cpp
- repeat_2nd_test.cpp

### #define BOOST_PP_REPEAT_2ND

Obsolete, just use BOOST_PP_REPEAT().

### #define BOOST_PP_REPEAT_3RD

Obsolete, just use BOOST_PP_REPEAT().
