BBC BASIC for Windows

Latest updates



The latest additions to the BBC BASIC for Windows online documentation, libraries and example programs are as follows:

If you want to update your local copy of the documentation to incorporate these additions, and at the same time upgrade your copy of BBC BASIC for Windows (plus its example programs and library files) to the latest version, proceed as follows:

The version number of BBC BASIC for Windows consists of a numeric part and a letter. If only the letter is changed, it signifies a trivial or cosmetic change, or a minor bug-fix. In general such changes will not affect any existing programs. If the numeric part is changed it signifies a more significant alteration or a bug-fix which might affect the operation of existing programs (for example if a program has inadvertently taken advantage of the presence of a bug).

The current version of BBC BASIC for Windows is 6.10a. If you have an older version and are unable to use the automatic upgrade facility please send an email giving your name and address and quoting your serial number. The following table details changes which have taken place since the beginning of 2006:
