matrix numbering and compare

Hi all,

I have stumbled on to 2 problems:

1) is there any way to show the index numbers for rows and columns of
a 2-dim matrix at the front panel ?
The aim is for the user to keep track of the coordinates in a fairly
large (80*16) table of list-boxes.

2) has anyone done some serious matrix comparing ? I mean, comparing
the user inputted matrix against a matrix, which describes
dependencies and reports an error if some cell values are conflict.

thanks,

andres

1) use 2 other arrays for this and update them each time the index is changed (or even strings but it will be more complicated)

2) with two for loops you can compare them cell by cell

p.s.: for both problems, probably an ActiveX "grid" control will be an easier solution.
