I noticed this as an unanswered question and decided to give it a go:

v=input().split('/')+input().split(',')+[input().split(' '),0,1,'X','U','D','L','R']
w,h,x,y,d,c,p,r,m,n,s,l,e=v
w,h,x,y=int(w),int(h),int(x),int(y)
g=[[' 'for x in range(int(h))]for y in range(int(w))]
while p&lt;len(c):
 i=c[p]
 if r:
  g[y][x]=m
 if i=='RESET':
  w,h,x,y,d,c,p,r,m,n,s,l,e=v
 if i=='DRAW':
  m='X'
 if i=='ERASE':
  m=' '
 if i=='UP':
  r=0
 if i=='DOWN':
  r=1
 if i=='DIRECTION':
  p+=1
  i=int(c[p])
  d=''
  if i in[8,1,2]:
   d+=n
  if i in[4,5,6]:
   d+=s
  if i in[6,7,8]:
   d+=l
  if i in[2,3,4]:
   d+=e
 if i=='FORWARD':
  p+=1
  i=int(c[p])
  for _ in range(i):
   if d.find(n)+1:
    y-=1
   if d.find(s)+1:
    y+=1
   if d.find(l)+1:
    x-=1
   if d.find(e)+1:
    x+=1
   if r:
    g[y][x]=m
 if i=='DISPLAY':
  for z in g:
   print(''.join(z))
 if i=='POSITION':
  print(x,y)
 if i=='SETPOS':
  p+=3
  x,y=c[p-2:p]
  d=''
  if i in[8,1,2]:
   d+=n
  if i in[4,5,6]:
   d+=s
  if i in[6,7,8]:
   d+=w
  if i in[2,3,4]:
   d+=e
 if i=='STOP':
  while input()!='~':
   pass
  exit
 if x&gt;w or x&lt;0 or y&gt;h or y&lt;0:
  print('!')
  exit
 p+=1



  PS I am unsure about the scoring setup so my score may be incorrect!
