c/Kate4
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

/* First function. This reads in all the arrays in one go. *
* The array returns an integer equal to the number of *
* frames read, to allow for expansion to cope with the *
* circumstance when a user aborts the read halfway *
* through. The arrays are passed to the function as *
* pointers rather than being copieds. Any changes to the *
* arrays in the function will therefore change the arrays *
* in main(), since they occupy the same address space. *
* The number of exposures on the film is passed as an *
* integer n. In this case it is a copy of n that is *
* passed, so any changes to n in readfilm() will not *
* affect the variable in main(). */
