*
*-----------------------------------------------------------------------
*
*Purpose:
* Modify a specific isotope and Autolib reaction in a Draglib.

*
*Parameters: input
* IPLIB LCM pointer to the Draglib.
* IMPX print index.
* NGRP number of coarse energy groups.
* NBIN number of fine energy groups.
* IMOD type of modification: =1: complete replacement; =2: replace
* specific values by VALUE; =3: increase by VALUE; =4: multiply
* by VALUE.
* TYPSEC name of reaction to modify.
* HISOT name of isotope to modify.
* VALUE value used in modification operation.
* IGM first energy group to modify.
* IGP last energy group to modify.
* NFS number of fine groups per coarse group.
* VAL array of values used if IMOD=1.
