Im using node red v3.02

I'm reading a cvs file with the cvs node and get the following messages out:

As you can see I have several ID's (ErrorCodes) and a corresponding text (ErrorText). I have another Node sending me the current ErrorCode (ID).

What I want to do is to initially read the file store it somewhere (in a global array??) and as soon an ErrorCode (ID) is given search for the corresponding text. I don't know where to store file information and I don't know how to read out the corresponding text

Perhaps someone out there can help me out
