There are several custom-installable packages of perl 5 that can be installed on 505.
There is also ksh already on the system which is much more functional (ah, pun not intended) than the plain sh.
It's safe to use ksh, it's stock since the later versions of xenix and it's on every box.

There are also several packages and standalone binaries of ksh93, bash, zsh.

You do not lack for scripting languages unless the site is only accessed by carrying floppies on foot through zombie hordes.

But, as for this:

> #!/bin/sh
> echo "calling function foo"
> foo "Dave"
> foo () {
> echo "$1 is not here"
> return 0;
> }
> # ./test.sh
> calling function foo
> ./test.sh: foo: not found

Shells read scripts from the top down and evaluate & execute things as they are encountered.

So, to use a function, first you define, then you use.

foo () {
echo "$0: $@"

foo well hello there
