Gaia Bytecode

Function IDs (aka Dependency IDs) are prefixed by an F.

F0 // Function ID = 0

Label IDs are prefixed by an L.

L0 // Label ID = 0

Comparison IDs are prefixed by a C.

C0 // Comparison ID = 0

Numbers are prefixed by a N.

N0 // Number = 0

Strings are prefixed by a S, followed by the strings length, and the string encoded as a series of numbers

S3 N102 N111 N111 // String = "foo"

Instructions are not prefixed by any character.

1 // increment pointer value instruction

ePU ROM Positions are translated.

CDP [10 12] [foo]

10 N10 N12 F0

Chronos VM Storage Format

Non-program data is stored with 00 appended before the actual data Program data is stored with 1 then the corresponding type indicator:

• 0 : Instructions
• 1 : F
• 2 : L
• 3 : N
• 4 : C
• 5 : S
