Multi-dimensional array bug

pobtastic

To demonstrate;

array one[3][6]
array two[3][6]

for x = 0 to len(one) loop
  for y = 0 to len(one[x]) loop
    one[x][y] = rnd(255)
  repeat
repeat

loop
  clear()

  printAt(0, 0, "one = " + len(one) + " two = " + len(two))

  update()
repeat

Output is: one = 6 two = 3

You'd expect the length of both the arrays to still match, right? After all, one is being populated correctly and if you view in the data inside one using 3*6 you can see everything in place ... but ... using len(one) actually returns you "6" and so, if you use len(one) again you get a nondescript error of Unrecognized type: 4 (what in the AMERICAN is this?!?!)

My workaround is to process it in rows;

array one[3][6]
array two[3][6]

for x = 0 to len(one) loop
  row = []
  for y = 0 to len(one[x]) loop
    row[y] = rnd(255)
  repeat
  one[x] = row
repeat

loop
  clear()

  printAt(0, 0, "one = " + len(one) + " two = " + len(two))

  update()
repeat

This is a bug that I already reported and is in the system. In a nutshell the upper bound of the 1st dimension grows to that of the 2nd dimension. In your case the 'two' array hasn't grown because you've not assigned anything to it. Had you done:

one[x][y] = rand(255)
two[x][y] = rand(255)

In the main loop then it would have suffered the same fate and they'd both have reported a size of 6 after the print statement.

Ah yeah that was there just to demonstrate the "correct" (expected) behaviour! Thank you

Has this bug been fixed?
