Sure have a ball. But the FourBit SUB means 4 bits.by (Login burger2227)
4 BPP means 4 bits per pixel. Yes the GET is one byte (an ASCII character representing a value), but the value is used as data for 2 pixels. Thus it is called a nibble mode.
I just used the loaders that were in Bob's Winbit program. All of the header info was there too, but I decided to use TYPE and one GET to load all of the bitmap info instead of loading one GET at a time. Doubt it really matters which way to do it. Perhaps it may be useful to a user and it helps describe how the header is designed.
If you will, post it in Bob's forum when you are done. I started with the Winbit code and worked my way up to the BSAVER.
