The BOOST_PP_REPEAT_FROM_TO_z macro represents a reentry into the BOOST_PP_REPEAT_FROM_TO repetition construct.

#### Usage

BOOST_PP_REPEAT_FROM_TO_ ## z(first, last, macro, data)

#### Arguments

z
  The next available BOOST_PP_REPEAT dimension.
first
  The lower bound of the repetition. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
last
  The upper bound of the repetition. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
macro
  A ternary operation of the form macro(z, n, data). This macro is expanded by BOOST_PP_REPEAT with the next available repetition depth, the current repetition number, and the auxiliary data argument.
data
  Auxiliary data passed to macro.

#### Remarks

This macro expands to the sequence:
macro(z, first, data) macro(z, first + 1, data) ... macro(z, last - 1, data)
The number of repetitions (i.e. last - first) must not exceed BOOST_PP_LIMIT_REPEAT.
At certain times, it may be necessary to perform the concatenation with BOOST_PP_CAT rather than the preprocessor token-pasting operator. This happens when the z value is a macro invocation itself. It needs a delay to allow it to expand. The syntax in such a scenario becomes:
BOOST_PP_CAT(BOOST_PP_REPEAT_FROM_TO_, z)(count, macro, data).

    #define TEXT(z, n, data) n data

    #define MACRO(z, n, data) /* ... */ \
      (                                 \

            TEXT, xyz                   \
         )                              \
