Most likely you're actually using bash syntax, not Bourne shell syntax.
Bash has a number of enhancements that are not supported by Bourne shell
(or the POSIX sh standard). However, because many GNU/Linux
distributions come with bash as /bin/sh, people who are learning shell
scripting on GNU/Linux often make the mistake of thinking bash features
are Bourne shell features.

Yes, functions are supported.
Since you don't give an example of what you're doing, we'll just have to
guess: I guess you're doing this:
function myfunc () {
...
}
This is not valid Bourne/POSIX sh syntax. The "function" keyword is a
bash-ism, and is not needed in Bourne/POSIX sh. Just write:
myfunc () {
...
}
If this isn't the problem, please provide a sample of the code you're
using and show us what errors you get when you try it.
Cheers!
