To run the converter on all the files use:

    convert path_to_h_files\ path_to_fi_files\
    
i.e.,

    convert d:\dev\watcom\os220_h\ fi\
    
the trailing backslash is req'd.

Pass 1 just scans for typing information.  It takes a fair amount of time
to run.  For that reason, if the inityp.awk file is kept around, pass2 can
be run alone.  It has the same parms as the convert.bat file.  i.e.,

    pass2 d:\dev\watcom\os220_h\ fi\
    
The file special.awk contains hand-converted types from files.  To add
more types (for example those which pass2.awk can't figure out) just add
them to special.awk.  For example, to add a structure named FOO and a type
which is a pointer to FOO, you'd add these lines:

    is_a_struct[ "FOO" ] = 1;
    is_a_reference[ "PFOO" ] = 1;
    
(Note there is no need to add 'conv_to_int[ "pfoo" ] = 4'.)
An integer type would be added like so:

    conv_to_int[ "WACKA" ] = 2;
    
Then all WACKAs become "integer*2".


xlat.awk

    This awk file can be used to see what sections of the header file
    are between XLATOFF and XLATON.  IBM has a program which converts
    H file to INC files for the assembler; it ignores everything between
    XLATOFF and XLATON comments.
