I love them:

Data 0,0,0,0
Data 0,0,0,4
Data 0,0,0,8
Data 0,0,0,12
Data 0,0,0,16



Local a[4]
Read a
For count=0 To 4
	Print a[count]
Next
WaitKey

or try

Local a[10]
Print Str(a)
End

How is that a bug?

It's a bug because the array is misused but Blitz3D doesn't catch the error.

Data 5
Local a[0]
Read a		; wrong, but compiler doesn't notice
a = 5		; similar error does get caught

Data 0,0,0,0
Data 0,0,0,4
Data 0,0,0,8
Data 0,0,0,12
Data 0,0,0,16

Local a[4]
Read a
For count=0 To 4
Print a[count]
Next
WaitKey

This gives me very strange numbers (but no error):
9961472
35788945
1
31
29426952

The big numbers are different each time, except the "1" and "31", they stay the same.

Local a[10]
Print Str(a)
End

This gives me MAV on the "Print Str(a)" line (v1.98).

i think the Data-thing just reads any memory. got an 1 and a 31, too.

Str() normally ignores type-converting errors for:

t.mytype=New mytype
t\lol=3
t\haha$="cool"

Print str(t);Prints [3,"cool"]
