The question still needs to be answered as to what shell you are using. The method you used to compute string length is correct for KSH.

What happens if /usr/bin/ksh is not present? It doesn't seem likely that it is since he stated that his remaining scripts do work. When I run sh on my system, I get the same error so it does appear that his default shell is sh and it does not support ${#var}.
