Im trying to create a project in which a softIoc receives many alarm fields, operates in them with the or "||" operator of the calc module and returns a value that represents the most severe activated status

Hi Marco—

Take a look at the Maximize Severity Attribute https://docs.epics-controls.org/en/latest/guides/EPICS_Process_Database_Concepts.html#maximize-severity-attribute

which can be used to propogate alarm severity across links. That may simplify what you are trying to do.

First question: am i doing it right? I noticed that when i first initialize the ioc and run "caget d:test1.STAT" i get "UDF"

Right. Before a record has been processed, it is invalid with a status of undefined (UDF). 

 one of the messages i get is "Error: Invalid character '|'" which i think is weird because the operator is in the calc documentation(?). 

Try quoting: 

field(CALC,"A||B||C")
