I (Grs (talk)) made an interpreter for this in Python. To enter a program, enter it line by line. Type run and press enter to run your code. Type exit and press enter to exit. It will only 1000 iterations of your code, because there is no stopping otherwise. Before running, remove the REMOVE_THIS texts, but do NOT remove the apostrophe characters! The code:

```def run(input_code):
# region CONVERT INPUT TO TABLE
longest_line_length = 0
for i in range(len(input_code)):
if len(input_code[i]) > longest_line_length:
longest_line_length = len(input_code[i])
code = []
for y in range(len(input_code)):
code.append('REMOVE_THIS')
for x in range(longest_line_length):
if x < len(input_code[y]):
code[y] += input_code[y][x]
else:
code[y] += ' '
# endregion
# region FIND LAUNCH POINT (&)
for y in range(len(code)):
for x in range(len(code[y])):
if code[y][x] == '&':
X_char = x
Y_line = y
break
# endregion
direction = 2 # LAUNCH DIRECTION: down
VARIABLE = 0
for i in range(1000): # you can change this line to while True: if you do not want the program to end
# region MOVE APPLE (@)
if direction == 0 and Y_line-1 >= 0: # up
Y_line -= 1
elif direction == 1 and X_char+1 < len(code[Y_line]): # right
X_char += 1
elif direction == 2 and Y_line < len(code): # down
Y_line += 1
elif direction == 3 and X_char-1 >= 0: # left
X_char -= 1
# endregion
command = code[Y_line][X_char]
if command == '+':
VARIABLE += 1
elif command == '-':
VARIABLE -= 1
elif command == '#':
if type(VARIABLE) == type(1):
print(chr(VARIABLE),end='REMOVE_THIS')
else:
print(VARIABLE,end='REMOVE_THIS')
elif command == '\$':
VARIABLE = input('\$ ')
elif command == '|':
if direction == 1:
direction = 3
