Two 1991 type-ins which were part of the "Utilitaires Pour OCP" published in the September/October issue of Amstrad Cent Pour Cent.
These programs allowed OCP compressed screens to be loaded and saved as uncompressed screens - useful for slideshows etc.
Once I have Listed the programs I display the excellent uncompressed (digitised?) screen using the VIDI Rom.
