P/TESTER
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.

File contents
Demo file showing the wordwrapper ================================= Say we have a block of text which was written in 80 column mode,but we want to show this is 40 column mode instead.A crude way to do this would be simply to print it out unmodified,but this would result in some words being broken across the ends of lines.It is therefore desireable to wordwrap the text.This may be done by considering some special cases. To do this - if you find a character LESS THAN or EQUAL TO 13 then a newline is printed,then,you look ahead one byte to see if that is also LESS THAN or EQUAL TO 13,but NOT the same as the other.This then takes into account people who wanted two empty lines one after another in their text.Discard the second byte if it IS different. 012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123
