Programming 23 Heading for Trouble
Continuing his codebusting theme, Terry Bulfib delves deeper into the loading methods used to 'protect' commercial software from the prying eyes of hackers. This month, he takes a look at programs claiming to be 'headerless'.
34 Routine Errors

Anyone can be an artist on the Spectrum - it's just a matter of co-ordination. Let Chris Somerville tell you where to draw the line.
66 Machine Code Commands
