KSH: Accessing individual words in a variable string (like arrays)

Kindly suggest the ksh equivalent of the following csh script snippet


##############################
set presidents=(Washington Adams Jefferson Madison Monroe Qunicy-Adams
Jackson)

echo $presidents[1] $presidents[4-7]
##############################

What version of ksh are you using? Try one of...

set - Washington Adams Jefferson Madison Monroe Qunicy-Adams Jackson
echo $1 $4 $5 $6 $7

set - Washington Adams Jefferson Madison Monroe Qunicy-Adams Jackson
printf "%s" $1; shift 3; echo "$@"


set - Washington Adams Jefferson Madison Monroe Qunicy-Adams Jackson
echo ${@:1:1} ${@:4:4}

presidents=( Washington Adams Jefferson Madison Monroe Qunicy-Adams
Jackson )
echo ${presidents:1:1} ${presidents:4:4}

Oops. The latter should have been...

echo ${presidents[@]:1:1} ${presidents[@]:4:4}

The only thing that I can get to work is the following:

presidents[0]=Washington
presidents[1]=Adams
presidents[2]=Jefferson
presidents[3]=Madison
presidents[4]=Monroe
presidents[5]=Qunicy-Adams
presidents[6]=Jackson

echo ${presidents[0]} ${presidents[3]}
##### Could not find the KSH equivalent for echo
$presidents[4-7]

echo ${#presidents[*]}


Is there some way to print a range of array elements?

Thanks

See my reply upthread...

In ksh93, bash, ... (otherwise use the 'set - ...' approach)

echo ${presidents[@]:1:1} ${presidents[@]:4:4}

The second second number defines the number of elements (if omitted
until the end of the array list)... ${arrayvar[@]:index:length}
