This solution has the risk of "forgetting" records of uncommon record types.
Anyway, I think it would be a nice feature for EPICS 3.15 to create an
empty string if a field does not exist:

     dbl * "RTYP PREC EGU DTYP DESC"

     test:1,"bi",,,"Soft Channel","desc of test:1"
     test:2,"calc","1","unit","","desc of test:2"
     test:3,"longout",,"unit","Soft Channel","desc of test:3"

That minor change would easy parsing the dbl output.
