This keyword data block is written by the DUMP operation. It is intended to be used to reinitialize simulations at the point that the DUMP command was executed or to transfer reactions defined by REACTION data blocks between IPhreeqc modules.
The REACTION_RAW data block contains a complete listing of the internal data structures that define a stoichiometric reaction (REACTION data block definition). REACTION_RAW data blocks are written by DUMP and read by PHREEQC without user modification. The formats should be considered dynamic because future modifications to PHREEQC could result in additional data that are included in the REACTION_RAW data block.
REACTION and REACTION_MODIFY.
