That is quite a useful book and it gave the equations for solving astronomival calculations on a scientific calculator.
A more useful book I found is the "Astronomy with your personal computer" by the same author.
This gives all the calculations in GWbasic form and is suitable for just about every astronomical calculation. The code is modularised so that all the sections can be assembled into different programs.
The code will work in Qbasic without modification but basic/qbasic will not work in Windows 7.
I have all the source on my computer (painfully entered by hand over a number of years) plus many programs using this source modified to make it more managable. I also have most of the code patched to run on the current version of QB64 which allows all the programs I have written to run in Windows 7 64 bit. QB64 will also run in Linux and on a Mac
The current version of QB64 does not recognise DEF FUN(W) or OPEN COM properly yet and also has some protected words that were available for use in Qbasic. The source needs to be edited to process this code differently not a major problem.
There are some programs here using the code from this book although not all these have been updated to QB64 state yet.
