IVRA is a register-based runtime. Around the runtime, layers of abstraction are created to use IVRA more simply.
Runtime auto-build is available for linux (x86_64) and for profanOS (i386).
v1 is in progress, if you are looking for v0 (in c++) watch the releases
00. DIS => display R(1) as a text if R(2) else as a number
01. SET => R(1) = (2)
02. CPY => R(1) = R(2)
03. TRC => R(R(1)) = R(R(2))
04. ADD => R(1) = R(1) + R(2)
05. SUB => R(1) = R(1) - R(2)
06. MUL => R(1) = R(1) * R(2)
07. DIV => R(1) = R(1) / R(2)
08. AND => R(1) = R(1) & R(2)
09. HOR => R(1) = R(1) | R(2)
10. NOT => R(1) = !R(1)
11. SUP => R(1) = R(1) > R(2)
12. EQU => R(1) = R(1) == R(2)
13. JMP => CT = R(1)
14. GIF => if R(1) != 0 then CT = R(2)
15. SCT => R(1) = CT
16. HLT => exit
