RE: "extract" command enhancement (subfiles and Biffs

["Hatzenbeler, Tim" <thatzenbeler@xxxxxxxxxxxxx>]

Scott,

The problem as I see it, to write procedures for a subfile or for any other
IO in general, at least to my knowledge, is you really can't make it
generic.  Because in your service module, you still need the real name of
the file or subfile you want to manipulate.  What I was trying to suggest is
this, before you can have real procedure to do file IO, you need the
features of File pointers....

i quickly pieced this together, but I hope the general concept has been
presented...

fp=open(SubCtl1)
ClearSubfile(fp)
close (fp)

fp=open(SubCtl2)
ClearSubfile(fp)
close(fp)

int closesubfile(const char *filename) {    <--- procedure interface
    FILE *f;
    /* set the clear indicator */
    write f
}

This example was a rpg/c combo that would never work, but I hope it made
since...
