open-weather.sqlrpgle Example

Hi all

I'm try to compile the source of open-weather.sqlrpgle that i found at
<https://github.com/fathert/json-rpg-example/blob/master/open-weather.sqlrpg
le>
https://github.com/fathert/json-rpg-example/blob/master/open-weather.sqlrpgl
e (Thanks to Tim Fathers) but i receive this errors:



Variable HOST, ENDPOINT APPID and not defined . Reason: No declaration
for the variable exists, the declaration is not within the current scope, or
the variable does not have an equivalent SQL data type.

At this program point :



// Execute the webservice call.

exec sql

set :response = systools.httpgetclob(

concat(:HOST, replace(replace(:ENDPOINT, '&CITY_IDS', :cities),
'&APPID', :APPID)),

:requestHeaders

);



can some one help me to understand where am i wrong ?

thanks in advance
