Every instruction starts with one-byte opcode, possibly followed by several operands. There are formal operand and instruction specifications.
ROSE supports some primitive types. Every type has constructor(s) and other instructions to work with. There are value types and reference types.
-
Integers are 32-bits signed numbers with usual arithmetic. Value type. Instructions:
int.*. -
Floats are IEEE-754 single precision floating-point numbers with usual arithmetic. Value type. Instructions:
flt.*. -
Arrays are containers of (references to) objects with random access. Reference type. Instructions:
arr.*. -
Byte arrays are containers of bytes/words with random access. Reference type. Instructions:
barr.*. -
Files are bytestreams used for input-output. Reference type. Instructions:
file.*. -
Objects are module instances. Reference type. Instructions:
obj.*.
