SYNOPSYS

PARAMETERS

char *string

int *nstrt

double *dreslt

int *jf1

int *jf2

DESCRIPTION

  Convert free-format input into double precision floating point,
  using slaDfltin but with special syntax extensions.

  The purpose of the syntax extensions is to help cope with mixed
  FK4 and FK5 data.  In addition to the syntax accepted by slaDfltin,

the following two extensions are recognized by dbjin

     1)  A valid non-null field preceded by the character 'B'
         (or 'b') is accepted.

     2)  A valid non-null field preceded by the character 'J'
         (or 'j') is accepted.

  The calling program is notified of the incidence of either of these
  extensions through an supplementary status argument.  The rest of
  the arguments are as for slaDfltin.

Given

     *string    char      string containing field to be decoded
     *nstrt     int       where to start decode (1st = 1)

Returned

     *nstrt     int       incremented
     *dreslt    double    result
     *jf1       int       dfltin status: -1 = -OK
                                          0 = +OK
                                         +1 = null field
                                         +2 = error
     *jf2       int       syntax flag:  0 = normal slaDfltin syntax
                                       +1 = 'B' or 'b'
                                       +2 = 'J' or 'j'

Called
