Usage

Usage for arrays

# Define array to be used and save it in a variable
array 1 2 3 end
  let my_array

# Use @ to read at a specific index of the array
my_array 1 @ # Result: 2
# Use ! to change the element at the index
my_array 790 1 ! # Changed 2 to 790

Usage for strings

# Create string to be used and save it in a variable
"fello"
  let my_string

# Use @ to read a character at a specific index of the array
# (the result is always a string of length 1)
my_string 2 @ # Result: "l"
# Use ! to replace the character at the index in the string
my_string 'h 2 ! # Now the string is "hello"
