Re: Speeding up array initialization

[Geoff Canyon]

First, remember that you don't have to initialize an array unless you 
have values you want in it. Without initializing anything,

put x[1,2] into y

is perfectly fine, and results in y containing empty.

In the case you listed below, what you want is something like this:

1,1 a
1,2 b
1,3 c
1,4 d
1,5 e
2,1 f
2,2 g
2,3 h
2,4 i
2,5 j
In the above the separator is a space, for ease of use in email. You 
need to use something that is guaranteed not to be in your index or 
data.

Given the above in a variable x,

split x using return and space

would give you the array you want.

So now you just need a way to go from the lines you have to the 
information above. Something like this will work:

  put empty into tNewData
  put 0 into tLineCounter
  repeat for each line L in tData
    add 1 to tLineCounter
    put 0 into tItemCounter
    repeat for each item T in L
      add 1 to tItemCounter
      put tLineCounter,tItemCounter && T & cr after tNewData
    end repeat
  end repeat

You can change your delimiters in the split, JB.  (The second cannot 
be
null, though.)  Build your value to be split appropriately.

Well, thanks for the advice, but I've already tried the split cmd in 
many
ways, but with no success...

Here's an example :
I have a variable S made of 2 lines of 5 items each :
    line 1 :    a,b,c,d,e
    line 2 :    f,g,h,i,j
how do I use the split cmd so that I get a 2 dimensions array S in 
which :
    S[1,1] = a
    S[1,2] = b
    S[2,1] = f
    S[2,2] = g
and so on...

Thanks,
JB
