cmlist01 has a b c d e
cmlist02 has f g h i
cmlist03 has j k l
For the total in cmlist01, I should see 5 items.
For the total in cmlist02, I should see 4 items.
For the total in cmlist03, I should see 3 items.
As a result, I could do:
print "There are ${#cmlist01[@]} items in $listnbr:"
which prints "There are 5 itmes in cmlist01."
However, I want to do all of this in a for loop and have it derive the cmlistnn from the variable $listnbr (which is does just fine as evidenced in the output from the print statement). However, if I try to get the count (number of items in the array) using listnbr (instead of hardcoding cmlistnn in each statement), all I ever get is 1.
If I set the variable listnbr=cmlist01, I should see 5 items, but am only seeing 1 when I do:
print "There are ${#listnbr[@]} items in $listnbr:"
which prints "There are 1 itmes in cmlist01."
The main part of the code that I need this for is:

news - print news items
SYNOPSIS
[items]
DESCRIPTION
is used to keep the user informed of current events. By convention, these events are described by files in the directory
When invoked without arguments, prints the contents of all current files in most recent first, with each preceded by an appropriate header.
stores the ``currency'' time as the modification date of a file named in the user's home directory (the identity of this directory is
determined by the environment variable only files more recent than this currency time are considered ``current.''
Options
recognizes the following options:
Print all items, regardless of currency.
The stored time is not changed.
Report the names of the current items without printing their contents,
and without changing the stored time.
Report how many current items exist without printing
their names or contents, and without changing the stored time. It is useful to include such an invocation of news in
one's file, or in the system's
All other arguments are assumed to be specific news items that are to be printed.
If an interrupt is typed during the printing of a news item, printing stops and the next item is started. Another interrupt within one
second of the first causes the program to terminate.
