Just a note about this question. I haven't found any way to delete the 'unused' symbols from the file (or to overwrite them), and don't know if they will ever be automatically purged.
But I have realised that it is possible to prevent an untold number of symbols being added to the file. I am now basing the symname parameter on the actual file name: I am appending a timestamp to the filename and using that as the symname parameter (the timestamp is based on the last modified date/time of the file to ensure that I can read a new copy of the symbol if the file is modified).
Initially I was using something like 'temp' but it was not possible to overwrite the symbol that had been read in subsequent calls. I then changed to using a different symname every time I called SymRead (this works, but has the potential to add an untold number of symbols to the file - not ideal, but probably not a problem in these days of massive amounts of storage and memory).

Thanks Josh,
You have answered my initial question, but I will leave my logic as it is for those who don't have this option set (which may be quite a few, as my default install of Dcad has 'Symbols(Automatic)=FALSE' and also 'Symbols(Manual)=FALSE').
