how to define an array

[David McFarlane]

Sihua,

Judging from your example, I take it that you have a background in 
C/C++, which has an elegant way of initializing arrays in 
code.  Standard VBA might include a similar (though more clumsy) 
mechanism, but that has been left out of E-Basic.  So as the previous 
respondant says, you just need to assign each array element in turn 
with its own assignment statement.  Of course you also need to first 
declare your arrays, thus,

     Dim  a(1 to 36) as Integer  ' use explicit array bounds to 
reduce confusion
     Dim  b(1 to 12) as Integer
     a(1) = 2
     a(2) = 3
     ...
     b(1) = 12
     b(2) = 7
     ...

and if you like you can collapse that using the colon statement separator,

     Dim  a(1 to 36) as Integer  ' use explicit array bounds to 
reduce confusion
     Dim  b(1 to 12) as Integer
     a(1) = 2: a(2) = 3: ...
     b(1) = 12: b(2) = 7: ...

but it is still clumsy and ugly no matter how you do it.  This is 
really elementary VBA programming, so for more info I recommend an 
intro VBA programming book such as "VBA for Dummies".

If it were me, I might instead use a List for initializing and 
randomizing, but that is more than I can go into here.
