Variable substitition

[Richard van de Stadt]

Is there some sort of variable substitution possible in a shell script
to get the value of the last argument supplied to the script? I don't
mean shifting the arguments until one is left. I'd like to know if something 
like awk's $NF, in which NF means the number of fields, and $NF means the 
value of the last field, is possible. ${$#} results in an error message.
