alias command not working on Solaris 9

When I add an alias it appears to work, but when I type the alias it says "alias not found". When I type the word "alias", the newly created alias is not in the list. I have also tried one of the aliases that is already in the list and I will get "alias not found".

$ alias

autoload='typeset -fu'

command='command '

functions='typeset -f'

history='fc -l'

integer='typeset -i'

local=typeset

nohup='nohup '

r='fc -e -'

stop='kill -STOP'

suspend='kill -STOP $$'

$ history

history: not found

$
