other way is to edit the web.config file and then use the 

GetConfigSettings() to read it

for example

String ls_key, ls_value
#IF DEFINED PBWEBSERVICE THEN
    ls_key = 'database'   
    ls_value = GetConfigSettings(ls_key)   
#END IF

Hi Doug;

     Yes you can access INI and other files deployed in a PB2017R2 Web service!

Have a look at my Web Service Framework. A good simple example of an INI being read by a Web Service is in the framework's OrderEntry example App.
