      SUBROUTINE MNPOUT(IUEXT,CHNAM,VAL,ERR,XLOLIM,XUPLIM,IUINT)
#include "minuit/d506dp.inc"
CC     User-called
CC   Provides the user with information concerning the current status
CC          of parameter number IUEXT. Namely, it returns:
CC        CHNAM: the name of the parameter
CC        VAL: the current (external) value of the parameter
CC        ERR: the current estimate of the parameter uncertainty
CC        XLOLIM: the lower bound (or zero if no limits)
CC        XUPLIM: the upper bound (or zero if no limits)
CC        IUINT: the internal parameter number (or zero if not variable,
CC           or negative if undefined).
CC  Note also:  If IUEXT is negative, then it is -internal parameter
CC           number, and IUINT is returned as the EXTERNAL number.
CC     Except for IUINT, this is exactly the inverse of MNPARM
