Thanks a lot for your help. I rechecked the man page with the
following command and confirmed the comments you told above:

$ man bash | egrep -A10 '^[ ]*declare \['
       declare [-aAfFgilnrtux] [-p] [name[=value] ...]
       typeset [-aAfFgilnrtux] [-p] [name[=value] ...]
              Declare  variables  and/or give them attributes.  If no
names are given then display the
              values of variables.  The -p option will display the
attributes and values of each name.
              When  -p  is used with name arguments, additional
options, other than -f and -F, are ig‐
              nored.
