\#This, for specific case 3, works:
\    set command = $entry3[1]
\    set prompt = "${entry3[2-]}"

Huh? I got `Variable syntax.' on the second assignment! Of course the above
SHOULD work.
The `3' ending the name of the variable seems to cause the trouble,
because the following DOES work:

	set prompt = "${argv[2-]}"

A workaround for our problem is:

	set prompt = "$entry3[2-]"	# forget the braces

\#This, for general case i, fails, with message 'Variable Syntax':
\@ i = 1
\while( $i <= $n )
\    set command = ${entry$i[1]}
\    set prompt = "${entry$i[2-]}"

	eval set command = '"$entry'$i'[1]"'
	eval set prompt = '"$entry'$i'[2-]"'
