DF 19.1

Hi,
I have been working my way through the warnings in DF19.1, I have just about cleared them all but I get a warning regarding the function MemoryGetByte being obsolete, but the function is called in the dataflex package.

I use cSeqFileHelper to save a binary image received via web service to file, I just want to check that I shouldn't be using some other class instead?

Regards,
Nicole
