ASTROL96, created in March, 1990, replaces ASTROL95, created in December,
1987. The impetus to replace ASTROL95 comes from the tendency of its
graphic chartwheel to freeze some 386 computers. ASTROL95 was a product
of the excellent but dated IBM Basic compiler 2.0. With Microsoft's
Basic compiler 7.0, I was finally able to produce a program which
approaches ASTROL95 in speed and size. For speed ASTROL96 uses the
alternate math library which does not emulate a math coprocessor in
software. For size, the ASTROL96.EXE file contains two overlay files
which are memory-swapped; CHKDSK need show only 212,000 free bytes.
While updating for more modern machines, some backward compatibility was
lost, as ASTROL95 will run under PC-DOS 2.0 but ASTROL96 requires 2.1.
ASTROL96 has many small improvements, most of which derive from work
on my commercial AstrolDeluxe program. I incorporated improvements into
ASTROL96 if I could do so without increasing the size of the program.
If anyone discovers problems or has recommendations for additions or
changes to the program, my Compuserve ID is 76317,547 and my address is:
