Creating an arrayI'm trying to create a simple array a[1] = "string 1"..... a[10] = "string 10"
I'm am creating this array by reading values from a table, while looping through with a FOR statement. I'm getting an error with the first reference to a[1]. (actually aand j is initialized and incremented correctly.
what am i doing wrong? I tried going though help, but I'm not finding what I'm looking for.
Thanks,Re: Creating an arrayYou don't need to use a For loop to get column values. Might be quicker to use GET VALUES:

PeterRe: Creating an arraythanks, that resolved my problem!Re: Creating an arrayYou probably need "a" to be a list. Try preceding your code with a line: a = {};
Then take a look in the scripting pdf docs for "Lists", "Associative Arrays", and Matrices (or Matrix).
