- All variables haves 1 Long Word, 2 Words, 4 Bytes, 8 Nibbles, 16 2Bits and/or 32 bits.
- Byte range 0-255
- Nibble range 0-15
- 2Bit range 0-3
- bit range 0 or 1
One Nibble Translated
- Binary = Decimal
- 0000 = 0
- 0001 = 1
- 0010 = 2
- 0011 = 3
- 0100 = 4
- 0101 = 5
- 0110 = 6
- 0111 = 7
- 1000 = 8
- 1001 = 9
- 1010 = 10
- 1011 = 11
- 1100 = 12
- 1101 = 13
- 1110 = 14
- 1111 = 15
- Note: Therefore Setting Bits 4-7 to 1 will make Nibble 1 15. Therefore Setting Bits 0-7 will make Nibble 0 & 1 15, and Byte 0 255
Linear Quest Var
- BYTE:
- 0: Step1.
- 1: Step2.
- ...
- 255: Step256.
- Nibble:
- 0: Step1.
- 1: Step2.
- ...
- 14: Step16.
Non-linear Quest Var
- BYTE: Main Quest Line
- NIBBLE: Current-Step
- BIT: Step
- BIT: Step
- BIT: Step
- BIT: Step
- NIBBLE: Sub-Quest
- 0-15: Step 1-16
- NIBBLE: Current-Step
Dev Note: There are plans to make 64 bit quest variables.
