current instructions are

Allowed input file syntax

C FLOAT (C is a char, FLOAT is a float)

Combinations

F distance (move turtle forward by 'distance', print line if pencil is down)
T angle (turn turtle by 'angle' (positive angle counterclockwise))
U (move pencil up)
D (move pencil down)

[ repetition (start of loop repeat until ']' 'repetition' times)
] (end of loop)

{ (remember coordinates and angle)
} (goto remembered coordinates and angle)

WARNING it is not allowed to cross [] and {} e.g {[}] or [{]}

This version is now capable of nesting the new [ and ] 'repetitions' repeat instructions. It does not support the old R 'repetitions' and E instructions!

Combinations

F distance (move turtle forward by 'distance', print line if pencil is down)
T angle (turn turtle by 'angle' (positive angle counterclockwise))
U (move pencil up)
D (move pencil down)

[ (start of loop)
] repetition (end of loop, jumps to last '[' for 'repetition' times)

{ (remember coordinates and angle)
} (goto remembered coordinates and angle)

NOT SUPPORTED ANYMORE
R repetition (repeat following operation until E operator 'repetition' times)
E (marks end of repetition block)

This version only supports the R 'times' and E instructions for repetition, which cannot be nested.
