# help with code and array calcs

M

#### Matt S

This function is supposed to take second-by-second data and do the following
procedure:
1) Store data in arrays (arrTime, arrInletT, etc.)
2) Label data into four Modes of operation. (arrLabel)
3) Use the labels to store the data into four arrays (arrMode1, arrMode2,
etc.)
4) Perform seven calcs on the four Modes and store them in a 2-dimensional
array that is pasted back into Excel. (arrValues)

The data goes in order, Mode 1 for 40sec, Mode2 for 6sec, Mode 3 for 10sec,
Mode4 for 4sec, then repeats. This procedure is done for 50hours.

Because I'm new to arrays, the code is very rough and ill-defined. I think
it might work up to the calculations portion, but where I try to find out the
number of elements of the mode arrays will not work. The number of seconds
dont really stay constant... for example, Mode 1 could be 38-42 seconds long.
I do not know how to find out the #sec for that cycle. I need something
else besides NumElements.

Can someone straighten out my mess and get this code to work??

THANKS SO MUCH!
Matt

Thanks Bernie,

I copy/pasted your code and am going through it now. I'll make up a list of
questions for you and paste it here, if you don't mind. I'd like to learn a
