I am sorry if this is a terribly basic question, but I am new to Multiprog. When I open and compile the OSCAT\_basic\_333, I get errors that seem to indicate that type or function “BUF\_TO\_STRING” is needed in the base code but not available. Similar errors occur with the network library. Can anyone provide me some guidance and assistance on this? Thanks very much.

Apologies, I did find an earlier post about PROCONOS firmware library, this looks like it will solve my issue. Thanks…
