ars_perl_qualifier($ctrl, $qual)Note that this is a fairly complex Hash and if all you want to do is see the qualifier in a readable form (and not interpret it) you might just want to call ars_Export and extract the readable qualifier from the return value of that routine.
undef.
      Example:
      ($parsed_qual = ars_perl_qualifier($c, $q)) || 
            die $ars_errstr;
      
      Hash: the hash returned by ars_perl_qualifier has these members:
 oper   = "and", "or", "not", "rel_op"
 left   = qualifier             (only for and, or)
 right  = qualifier             (only for and, or)
 not    = qualifier             (only for not)
 rel_op = rel_op                (only for rel_op)
a rel_op is:
 oper   = "==", ">", ">=", "<", "<=", "!=", "like", "in"
 left   = FieldValueOrArithStruct 
 right  = FieldValueOrArithStruct
FieldValueOrArithStruct is:
 fieldId        = integer 
 value          = scalar value (integer, string, float, etc.) 
 arith          = ArithOpStruct 
 statHistory    = StatHistoryValue
 valueSet       = list of scalar values 
 variable       = integer       /* I think this is for passing
                                   macro arguments */ 
 queryValue     = QueryValueStruct 
 queryCurrent   = integer
StatHistoryValue is:
 userOrTime     = integer (1 = user, 2 = time)
 enumVal        = integer
ArithOpStruct is (a binary tree basically):
 arith          = operation ("+", "-", etc)
 left           = ArithOpStruct
 right          = ArithOpStruct
 value          = scalar value
 field          = 
 process        = scalar value
 function       = function
 dde            = not supported
