On page 126, the green books states:

"The data acquisition procedure used in a particular instance depends
upon the amount and nature of the data making up the image."

I understand this is also true for the length of the DataString used
i.e. it has to match the length of the image in question.

Now, lets say my file has tens or hundreds of bitmaps/images. Is there 
really no way to write a general purpose proc for data acquisition so 
that I merely would need to specify the width, length, depth and matrix 
for the image and then execute this generic image-display proc which
would read the data as printable hex from currentfile ?  Seems like 
a really stupid limitation so I believe there must be a way...
If anyone has a solution I'd very much appreciate hearing about it.

I have a feeling this must be extra trivial but I'll summarize if 
appropriate...
