Am I using valid array logic?

[jcm21]

P.P.S. This is a 2nd edit.
The code shown below boils down to the question "are the following 4 statements in the code shown below valid for storing and retrieving array elements"?
MyArray[DAY_NUM,1] = day_date;
MyArray[DAY_NUM,2] = open(0);
array_element = MyArray[x,1];
array_element = MyArray[x,2];




P.S. This is an edit: I think maybe I should have submitted this to the EFS studies forum. Sorry about that.

/* Am I using valid array logic?

If you are trying to create a multidimensional array then that is not the correct syntax. You may want to reference the examples for multidimensional arrays provided by Jason and Jay in this thread. Also if you run a search using the keyword multidimension* you should find an extensive write-up on arrays (complete with sample scripts) that was compiled by Steve Hare

Thanks Alex.
The results of my searchs in the last couple of days indicated to me that it all seemed so unnecessarily complicated that I decided to just create a one dimensional array for each column in an otherwise multi-dimensional array. Works fine for me [ie] it is simple & non-cumbersome.
Why can't an array simply just be defined as multi-dimensional in one statement and that would be that [eg] my_array(10,10) ? That has worked wonderfully in other languages for half a century.
However I am plenty happy with the editor and the language syntax.
Thanks again.
