My only critisism of these centres on UNSPOOL, for which only source is supplied, as it would not compile with M80 until tweaked a little. This is one program that should have been supplied as a COM file. Having said that, the source of UNSPOOL supplies the solution of how to write programs that can relocate themselves (and also reveals the purpose of the ‘r’ on every second line of SYS listings).

Well that was a brief review! Not so much a review as a list of what’s on the disk. Considering the number of useful programs packed onto the disk it must be value for money as are both CCPZ and BDOSZ.

This magazine also represents excellent value for money (a Superbrain friend of mine eyed it enviously). Readers, support your magazine with more letters and articles; Editor, what has happened to all the issues this year?
