Dictionary

|
|
A dictionary entry has this structure:
|
|
|
|
- Xb name. Arbitrary long number of character (but can't be
|
|
bigger than input buffer, of course). not null-terminated
|
|
- 2b prev offset
|
|
- 1b size + IMMEDIATE flag
|
|
- 1b code pointer (always jumps in the <0x100 range)
|
|
- Parameter field (PF)
|
|
|
|
The prev offset is the number of bytes between the prev field
|
|
and the previous word's code pointer.
|
|
|
|
The size + flag indicate the size of the name field, with the
|
|
7th bit being the IMMEDIATE flag. (cont.)
