Very Computer

I could really use arrays in the bourne shell.  In order to fake it I'm
trying to tack the subscript onto a common name, that is:

foo0="first"
foo1="second"
foo2="third"

for i in 0 1 2
do
        name = foo${i}
        echo $name <and the value of the name>
done

This correctly sets name to foo0, foo1, and foo2 but damned if I can get
"first", "second", "third" out of the thing with any combination of ', ", \,
{}, or $.

My real program has many more than 3 foos, and there are going to be about
20 lines of processing inside the for loop.  There are also 3 'arrays',
that is, I've got foo[100], bar[100], and blatz[100].  

It's not possible to change to another shell, write the routine in C, use
perl, or take any other easy outs.  It is possible for me to unroll the
loops, but I'd really like to avoid having 100 blocks of code that differ
only in the variable names.

thanks

Try this:

foo0="first"
foo1="second"
foo2="third"

for i in 0 1 2
do
        name=foo${i}
        eval "value=\$$name"
        echo $name $value
done

There is one (only one) "array" in the Bourne shell, it can be set with
the "set" command, and its members are $1, $2, $3 etc.

Quote:> foo0="first"
> foo1="second"
> foo2="third"
> for i in 0 1 2
> do
>    name = foo${i}
>    echo $name <and the value of the name>
> done

set first second third
for i in $*
do echo $i
done
