BIN

 The BIN function returns a character-string value  that  is  the
 binary  equivalent of the specified parameter.  The return value
 is compatible with all other string types.


 Syntax:

    BIN( x [[, length[[, digits]]]] )


 The parameter 'x' is  the  expression  to  be  converted.   This
 parameter  must  have  a  size that is known at compile time; it
 cannot be VARYING OF CHAR, a conformant parameter, or  a  schema
 type.

 Two optional  integer  parameters  specify  the  length  of  the
 resulting string and the minimum number of significant digits to
 be returned.  If you specify a length that is too short to  hold
 the  converted  value,  the resulting string is truncated on the
 left.

 If you omit the  optional  parameters,  the  bit  width  of  the
 converted  parameter  value determines the string length and the
 number  of  significant  digits.   By  default,  the  number  of
 significant digits is the minimum number of characters necessary
 to express all  the  bits  of  the  converted  parameter.   This
 default  length is one character more than the default number of
 digits, which causes a leading  blank  to  be  included  in  the
 resulting string when both parameters are omitted.
