A machine code program created from Basic by Paul Lay

Degas Fading Slideshow provides a continuous slideshow of all Degas format pictures on a disk fading each into view in a similar manner to several such programs available for the Atari 8-bit systems.

The program will automatically select only those pictures that correspond with the resolution in which the program is run provided that the standard DEGAS extenders are used. If there are no files on the disk that match the screen resolution the program will return to the desktop otherwise it will display all pictures in a continuous loop.

The main listing can be typed in using ST BASIC and will generate the appropriate object code which can be run in the normal wav. For those who wish to delve more deeply the Assembler source code is also given. This is quite useful as it shows that quite complex operations, such as file processing, are made easy by the GEMDOS, BIOS and XBIOS routines.

Note: FADER will only run with 512k machines. Owners of 1 Meg machines should first run MAK512.TOS or a similar program available in the public domain from your local user group or from PAGE 6.
