Merge Lists

[DroopyPawn]

Is there a way to merge lists when you don't know how many numbers are in each list?

I'm trying to create a dynamic stem-and-leaf plot problem (still).

I'd like to MakeList a list of numbers for each row in the plot as follows.
aList = 90 to 99
bList = 80 to 89
cList = 70 to 79
dList = 60 to 69

The length of each list will be random based on aCount, bCount, cCount and dCount.

Is there a way to merge all of those numbers into one unsorted list called zList?
Then zCount = aCount + bCount + cCount + dCount

I can use some if statements to make the leaves for each row in the plot.

There appears to be no way to actually combine two or more lists into one list and retrieve all the data values reliably. I have written a little bank that may serve as a starting point in generating dynamic stem-and-leaf questions. I have uploaded it into your Stem-and-Leaf Plot topic in ExamView Question Bank Exchange.
