!BasicProg/!Help

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.

Back to Basics: Learning to Program in Basic
By Mark Moxon

Run this application to open a directory containing four example Basic programs from the second part of the series on learning to program in Basic.

Listing1 prints out the value of the variable number_of_eggs at two different parts of the program.

Listing2 prints out the values of the variables number_of_eggs% and more_eggs%.

Listing3 demonstrates the use of string variables.

Listing4 shows various functions on numerical and string variables.

For more information, see the article on page 79.
