How to *LOAD a Teletext screen dump

Post by Josgrp »

In the good old 80's there was an online banking service from the Dutch Postbank called Girotel, based on the videotex protocol.
I am trying to resurrect this service (only locally!) in BBC Basic. I use B2, the BBC emulator for macOS.
But I'd like to switch to BBCSDL. For this I need to be able to *SAVE and *LOAD the teletext screen memory.
Is this possible with BBCSDL?

Check out PROCsave and PROCload in examples/general/telstar.bbc

Hated Moron, thanks for your answer!
I indeed tried this (BGET# and BPUT#) in The BBC emulator. But since it was too slow I switched to *LOAD and *SAVE.
But of course in BBCSDL there's no performance problem with reading and writing bytes from a data file.
Now I can continue my programming of Girotel with the very nice IDE from BBCSDL.
The only point is that I now have to export all the screen dumps I made with the emulator to separate disc files.
But this can easily be done with ADFS Explorer from John Welch.
