HFE Creator

(draft)

HFE directive allow you to create and write in multiple HFE files (no edit)

HFE INIT,'filename.hfe'

HFE CLOSE

HFE SIDE,face

Select current side

HFE TRACK,piste

Select current edited track.

HFE ADD_TRACK_HEADER

Add a track header to the current track

HFE ADD_SECTOR,track,side,ID,SectorSize,offset (current bank)

Add a complete sector to the track. Data from Rasm at Offset of the current bank.

HFE ADD_GAP,gap_size[,GAP value]

Add one or more bytes to the track. Default value is 0x4E like regular GAP filler.

HFE COMPLETE_TRACK

Complete the current track until 6250 bytes size

Byte Mode

HFE START_CRC

In byte mode, this directive starts a new CRC calculation (useful to write a sector header or data-CRC)

HFE ADD_BYTE,byte_value,…

Add a byte to the current track. To add synchro-byte (0xC2 and 0xA1 are supported), you must OR the byte with SYNCHRO (see advanced example)

HFE OUTPUT_CRC

Output 2 bytes of the current CRC to the current track.

Basic exemple, DATA floppy
