|Post subject:||Retrieve historical data|
I am trying to retrieve some historical data. I know hoe to get current time tokens with the file names like ".../@Y@M@D@X_upa.wmo." What I want to do is to get time tokens of the previous day (e.g. D-1). Is there anyway to assign a variable to some thing like V1=D-1, then have a file name .../@Y@M@V1@X_upa.wmo?
