 117 This function is not exported.
 118
 119 The following will be set where applicable:
 120  $flags->{CHARGES}->{amount}        Amount of debt
 121  $flags->{CHARGES}->{noissues}      Set if debt amount >$5.00 (or syspref noissuescharge)
 122  $flags->{CHARGES}->{message}       Message -- deprecated
 123
 124  $flags->{CREDITS}->{amount}        Amount of credit
 125  $flags->{CREDITS}->{message}       Message -- deprecated
 126
 127  $flags->{  GNA  }                  Patron has no valid address
 128  $flags->{  GNA  }->{noissues}      Set for each GNA
 129  $flags->{  GNA  }->{message}       "Borrower has no valid address" -- deprecated
 130
 131  $flags->{ LOST  }                  Patron's card reported lost
 132  $flags->{ LOST  }->{noissues}      Set for each LOST
 133  $flags->{ LOST  }->{message}       Message -- deprecated
 134
 135  $flags->{DBARRED}                  Set if patron debarred, no access
 136  $flags->{DBARRED}->{noissues}      Set for each DBARRED
 137  $flags->{DBARRED}->{message}       Message -- deprecated
 138
 139  $flags->{ NOTES }
 140  $flags->{ NOTES }->{message}       The note itself.  NOT deprecated
 141
 142  $flags->{ ODUES }                  Set if patron has overdue books.
 143  $flags->{ ODUES }->{message}       "Yes"  -- deprecated
 144  $flags->{ ODUES }->{itemlist}      ref-to-array: list of overdue books
 145  $flags->{ ODUES }->{itemlisttext}  Text list of overdue items -- deprecated
 146
 147  $flags->{WAITING}                  Set if any of patron's reserves are available
 148  $flags->{WAITING}->{message}       Message -- deprecated
 149  $flags->{WAITING}->{itemlist}      ref-to-array: list of available items
 150
 151 =over
 152
 153 =item C<$flags-E<gt>{ODUES}-E<gt>{itemlist}> is a reference-to-array listing the
 154 overdue items. Its elements are references-to-hash, each describing an
 155 overdue item. The keys are selected fields from the issues, biblio,
 156 biblioitems, and items tables of the Koha database.
 157
 158 =item C<$flags-E<gt>{ODUES}-E<gt>{itemlisttext}> is a string giving a text listing of
 159 the overdue items, one per line.  Deprecated.
 160
 161 =item C<$flags-E<gt>{WAITING}-E<gt>{itemlist}> is a reference-to-array listing the
 162 available items. Each element is a reference-to-hash whose keys are
 163 fields from the reserves table of the Koha database.
 164
 165 =back
 166
 167 All the "message" fields that include language generated in this function are deprecated,
 168 because such strings belong properly in the display layer.
 169
 170 The "message" field that comes from the DB is OK.
