FROM and EXTRACT commands.
----------------------------

    In C-- there are very original commands, which are not present in other
languages. It FROM and EXTRACT.

    The FROM command has syntax:

<type_variable> <name_variable> = FROM <name_file>;

    By meeting this command at compilation, the compiler will load in output
the file contents of the file <name_file>, and <name_variable> will be the
identifier beginnings of the loaded code. Here an example of use of this
command from the file tinydraw.c--:

byte palette [PALSIZE] = FROM "TINYDRAW.PAL"; // buffer for palette

   The EXTRACT command has syntax:

<type_variable> <name_variable> = EXTRACT <name_file>, <beginning>, <length>;

    By meeting this command at compilation, the compiler will load in output
the file from the file <name_file> number byte equal <length> from offset
<beginning>, and <name_variable> will be the identifier of a beginning of the
loaded code. Here an example uses of this command:

byte LIT128 = EXTRACT " 8X16. FNT ", 16*128, 16;
byte LIT130 = EXTRACT " 8X16. FNT ", 16*130, 16;
