    Data2Inc is a heavily modified version of msg2inc.pp which compiles the
     inputfile to include files containing array of char( or byte) typed
     constants.

     (e.g. CONST xxx : ARRAY[0..xxx] OF CHAR =( aa,bb,cc,dd,ee); ,
     or the same but ARRAY OF BYTE )

    Two types of input file are allowed:

    1 A special kind of textfile. Records start with '!'name and all following
       non empty and non comment (starting with '#',':' or '%') lines until
       the next line starting with '!' or EOF are the data. Data are either
       plain text (with \xxx ordinal constants) lines or a kinbd of
       Basic DATA command (these lines start with DATA).
       See demo.txt included with this package for a commented example.

    2  (special parameter -b)
       An arbitrary binary file can get converted to constants. In this mode
        only one constant per include file is possible.
