Post Re-written

Language specs:

LD <reg>, (<sym><num> | "*"<label>) LOAD
CMP <reg>, (<sym><num> | "*"<label>) COMPARE
ADD <reg>, (<sym><num> | "*"<label>) ADD
SUB <reg>, (<sym><num> | "*"<label>) SUB
ST <reg>, (<sym><num> | "*"<label>) STORE
JMP <label> JUMP if flag == 2
JGT <label> JUMP if flag == 1
JLT <label> JUMP if flag == 4
CLR <- clear the screen buffer.
i <- input stream
P <- display entire screen

<label> ::= "a-zA-Z0-9_"
":"<label>"$"<num> 
"@"<label>

RAM Mapping
RAM[39998] = keyboard input
RAM[40000 - 65000] = Screen Memory

Registers
Acc -> Accumulator
X -> Register X ---| General Purpose Register
Y -> Register Y ---| General Purpose Register

1 bit per pixel
Allowing 8 pixels per byte.

This looks very interesting and I am excited to try it out!

vinicity

This is insanely cool! You made a working computer language within Fuze! Super impressed!

LucasJG25

@JMM161437 thanks! :D

LucasJG25

@vinicity Thanks! Always wanted to try making an interpreter.

PickleCatStars

Esoteric indeed!

JMM161437

I've never heard of Esolang nor seen anything like it but it kinda reminds me of assembly the way to describe the functions of each instruction . Which makes me even more excited!

LucasJG25

@JMM161437 Very happy that you're excited! I'm looking forward to see what you'll do with this esolang.

JMM161437

@LucasJG25 I just tried to download it and nothing... is it still pending?

pianofire

@JMM161437 I think it was approved but has been updated so is awaiting approval again

LucasJG25

@JMM161437 Sorry about that. I had to make a last minute fix.

LucasJG25

@JMM161437 It's live now

JMM161437

Thanks I'll definitely check it out!

JMM161437

So it's a bit of a learning curve for me but wow is it amazing... Sorry if I seemed over excited just a fan of programming in a new way!

LucasJG25

@JMM161437 That's ok :D. Glad you like it.

LucasJG25

Ok so. I've ported this esolang to windows via C. And I made a bit of changes to the language.

The instructions are the same. But it's how you write the code.

The code above uses the ':' to separate each line of code.
ex:
I 0 : i : L 255 : P : C 0 : J 0 : j 0

On the windows port I removed the ':' so now you have.
ex:
I0 i L255 P C0 J0 j0

If Y'all prefer the second syntax I can make changes to the code to accept this syntax instead of the first.

vinicity

Hmm, how do I do subtraction and comparisons with ">" or "<"?

LucasJG25

@vinicity You subtract by adding 255 to the said number. Example: (I 5 : A 255) This makes Acc become 4. Since Acc when it has reached the highest amount of bits within the range of 0x00 to 0xFF. resets itself to 0.

Comparisons are done using the C instruction. So the capital C compares an immediate value with Acc. There are no negative numbers in this VM. So if you are for example at 0 and want to loop until you reach 5. You'll need to store the amount of loops in RAM or in register X and then compare if that number has reached 0, since you will be subtracting RAM/ register X after each loop.

Thought I'd try writing a BrainF interpreter in my esolang. Wrote this on the windows version. It should work for the FUZE4 version as it's the same VM and same code.

the most I could make was a simple calculator for addition o.o
