SUBROUTINE PCREIR(NMDEPL,MD2,NEL,ITNAM,ITZEA,KPAX,BPAX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Read depletion data on input file. Based on LIBEIR.f routine in
* DRAGON.

*Author(s):
* A. Hebert
*
*Parameters: input
* NMDEPL names of reactions:
* NMDEPL(1)='DECAY'; NMDEPL(2)='NFTOT';
* NMDEPL(3)='NG' ; NMDEPL(4)='N2N';
* etc
* MD2 dimension of arrays ITNAM, ITZEA, KPAX and BPAX
*
*Parameters: output
* NEL number of particularized isotopes including macro
* ITNAM reactive isotope names in chain
* ITZEA 6-digit nuclide identifier
* atomic number z*10000 (digits) + mass number a*10 +
* energy state (0 = ground state, 1 = first state, etc.)
* KPAX complete reaction type matrix
* BPAX complete branching ratio matrix
