Basic Array Tutorial Question

I am having a hard time using arrays.

I need to do such basic tasks as converting a text field 10 characters long to 10 one character array fields.

I also want to lookup an array using a search word and getting back an index. I know you must have such a tutorial but I can't find it.

I have been using substring functions but it is very ineficient.

You will not get a faster solution than using substring. Substring should be very very fast for a 10 characters string.

Can you post some code, demonstrating what takes too long?

Bad array samples

It would be nice to have the correct array equivilents. These work but take took much code and are not efficient.


Load 10 character field to ten 1 character array elements
-------------------------------------------------------
dim x as int
dim y as int


For x= 0 To 9
y=x+1
let(x)=word1.SubString2(x,y)
Next


A silly example of an array look up and update (lookup "a" make it "?"
----------------------------------------------------------------
For x=0 To 48

if let(x)="a" Then
let(r)="?"
End If

Next

I need to do such basic tasks as converting a text field 10 characters long to 10 one character array fields.

Can you use ToChars, or failing that use StringToBytes then CharsFromBytes?

Have a look at this Library

And a big help, if you want an array that can change sizes, use the list variable type
