multiple assignment to array
freezing or not depends on specifyng array type
Hi Eros
in this recent thread while reading Petr answer
i have tried this example :
Uses "console"
Dim a(10) As Long
a(4)=2,4,6,8,5,6,3,2
PrintL a(1)
PrintL a(4)
PrintL a(5)
WaitKey
this will output 0, 2, 4 as expected, without freezing.
but suppose i forgot to specify long type in dim a(10)
the program print the correct answer but hange
and the hanging are only from a(4), a(5), and up.
but it does not hang when we write
a(1)=2,4,6,8,5,6,3,2
or a(2)=2,4,6,8,5,6,3,2
or a(3)=2,4,6,8,5,6,3,2
if we reduce the items like
a(4)=2,4,6,8,5 it will not hang

Hi Zak,

thanks a lot for reporting this issue!
It is odd it does not fail for LONGs as well
Uses "console"
Dim a(10) As Long
a(4)=2, ' -- assigns to a(4)
     4, ' -- assigns to a(5)
     6, ' -- assigns to a(6)
     8, ' -- assigns to a(7)
     5, ' -- assigns to a(8)
     6, ' -- assigns to a(9)
     3, ' -- assigns to a(10)
     2  ' -- assigns to a(11) -> that is not defined!
     
PrintL Join$(a, ",")     

WaitKey
I think in this case the error 400: Subscript out of range in array or matrix should be fired, to avoid confusion


Petr

P.S. What does it mean when you do this?:
dim a(10)
... it does not mean forgotten type, but in fact it is equivalent to:
dim a(10) as variant
For reason unknown, the variants were more sensitive for the improper assignment above, but at least it helped us find the issue! :)
