MazeLang

This is not a Works-in-Progress. You're invited to add more examples, or more commands(if LXGW WenKai Mono GB supports and shows full-width).

MazeLang is designed by PSTF which is inspired by Befunge.

It uses ideographs instead of letters.

Plot introduction

Once upon a time, there was a boy(Mark Dreelmitex Gluzturzarzium, MDG for short), he's interested in adventure.

One day, MDG walks to a flat place. Suddenly, he floats up, and blew away by wind. He's scared, and screamed.

He lands in a maze. Now he lost in the maze, every program is a map for this maze.

Command List

＋: Pop a and b, push a+b.
－: Pop a and b, push b-a.
＊: Pop a and b, push a×b.
／: Pop a and b, push the quotient of a÷b.
％: Pop a and b, push the remainder of a÷b.
✗: Pop a, push 1 if a=0, otherwise 0.
＞: Pop a and b, push 1 if b>a, otherwise 0.
→: Goes east.
←: Goes west.
↑: Goes north.
↓: Goes south.
↕: If stack-top value is 0 then goes south, otherwise goes north, 
and discard the stack-top value regardless with the direction.
↔: If stack-top value is 0 then goes east, otherwise goes west, 
and discard the stack-top value regardless with the direction.
○: Goes in random direction.
＂: Collect every value of character until meet next ＂. 
If meet the half-width character, only first character will detected.
￤: Duplicate stack top.
⇄: Swap the top two elements of stack.
♨: Pop top element of stack, and then discard it.
Ｉ: Input number.
Ｏ: Output stack-top element as number.
ｉ: Input character.
ｏ: Output stack-top element as character.
▓: A bridge.
Ｇ: A "get" call (a way to retrieve data in storage). 
Pop two values y and x, then push the ASCII value of the character at that position in the program. 
If (x,y) is out of bounds, push 0.
Ｐ: A "put" call (a way to store a value for later use). 
Pop three values y, x and v, 
then change the character at the position (x,y) in the program 
to the character with ASCII value v.
If v means a half-width character, a space is automatically added, 
because MDG will only collect first character.
●: Sucks MDG out from the maze, thus end the program.
０１２３４５６７８９: Push the corresponding number onto the stack.
■: A wall, MDG will bounce back when he collide with wall.
◆: No operation.
☞: Pop s, and jump forward in this direction for s characters.
MDG will appear in opposite edge if he hits any edge.
☒: Clear the stack.
♬: Pop x and y, beep with tone x and time y. 
X will be pop first. 60 for Center C(C4). 1 for crotchet note.
◉: Throw MDG out immediately, with top stack value as exit code.
？: Pop a and b.
Turn right if a>b,
turn left if b>a, 
do nothing if a=b.
▪: Pop all stack item and join then into string, then reverse it, 
then load all command from this library.
▫: Exclude all library.
▶: Turn right.
◀: Turn left.
