ksh syntax - help!

[southbeach]

Working on a script and came across a do:while where

typeset -i n=1
until [ ${n} -gt ${#CF1[@]} ] ; do

... code ...
... code ...
... code ...

done

What is ${#CF1[@]}?

It seems to me like it is an array of sort.  If that is the case, where does it get its values?

Thanks,

PHV, I though that's what it was but is it a SYSTEM built in based on passed parameters/arguments?

In the script I am looking at, this array is used by reference and one of them is as noted in my original post. The 2nd reference simply transfer the value to a simpler variable.
