the proposed script uses few features and doesn't really push the limits of 
POSIX:
 - variables
 - if statements
 - for/while loops
 - functions
 - `local`
 - `export`
 - `return`
 - math with $((...))
 - printf
 - $IFS
 - `[` test
 - `read`
 - $#/$*/$1 positionals

i don't have a Version 7 shell, but wikipedia indicates those are all 
available
