PH Web and BLOBS

[Deskin, Bob]

DO BLOB is not supported in PH Web at this time. Allowing a portion of the DO BLOB functionality, specifically copying BLOBs to an external file, is being considered for a future release.

JP:

In Harold's case this may work. His code most likely is generating a 
differently named
