Gary,
I just got to try your suggestion. The blob field is part of a view. When I try the code you suggest:

FOR nIx = 1 TO nBlobSize
nBlobData[nIx] = SUBSTR(BlobData, nIx, 1)
ENDFOR

Where, BlobData is the name of the blob field in the view. I get the following error message:

Function argument value, type, or count is invalid

I get the sam error if I use vMyView.BlobData as the first argument.
Again, thanks for your suggestions.
Jim
