Besides normal Windows files, HTBasic supports legacy HP files that are "typed" as BDAT, ASCII, or PROG. The file type is stored in the first two bytes of the 256 byte file headers for HTBasic (512 or 768 bytes for HP LIF). HP PROG files must be saved in ASCII.
HP BASIC support files without a type that are labeled "HP-UX" files when present on a LIF or UNIX volume. A regular file is created with the CREATE statement as opposed to CREATE ASCII or CREATE BDAT.
