 BITTOC()
 Converts position-dependent bits into characters
------------------------------------------------------------------------------
 Syntax

     BITTOC(<nInteger>,<cBitpattern>,[<lMode>])
         --> cCharacterstring

 Arguments

     <nInteger>  Designates a number in the range of 0 to 65535, which
     corresponds to a bit pattern.

     <cBitpattern>  Designates a character string with a maximum of 16
     characters.  Each character corresponds to a bit in <nInteger>, where
     the last character corresponds to the lowest-value bit.

     <lMode>  When this optional parameter is designated as .T., 0 bits
     change to blanks.  The default is no change.

 Returns

     The returned string contains the corresponding characters passed by the
     bit pattern.

 Description

     The BITTOC() function changes the bits of a number into a sequence of
     corresponding characters.  This facilitates work with such bit-coded
     information as file attributes.  Depending on the <lMode> logical
     parameter (the l in lMode symbolizes logical), 0 bits either displays no
     character (.F.) or a blank (.T.).

 Note

     .  If <lMode> is designated as .T., the string length that
        results always corresponds to <cBitpattern>.

 Examples

     .  Change file attributes:

     .  The number 2 corresponds to a binary "00000010":

        ? BITTOC(2, "ADVSHR")            // "H" as the next to
                                         // last character

     .  The number 5 corresponds to a binary "00000101":

        ? BITTOC(5, "ADVSHR")            // "SR"

     .  The number 5, with the 0 bit displayed as a blank:

        ? BITTOC(5, "ADVSHR", .T.)       // "   S R"
