Original-subject: UBASIC 8.15 now available.
Reposted-by: emv@ox.com (Edward Vielmetti)
UBASIC 8.15 is now available for anonymous ftp at shape.mps.ohio-state.edu
in the directory pub/msdos/ubasic.
This new version eliminates some (known)
bugs in the earlier version 7.25 and has programs for factoring numbers
using the Multiple Polynomial Quadratic Sieve (on 386 machines with some
memory and hard disk requirements).
I include some update information.

SQRT of complex numbers having negative real part worked
not good:
ex. point 4:sqrt(-1+#i*0.1^10) caused division/0 error.

Rational arithmetic: ex. 1//2+1//3 is 5//6
Manipulation of strings:
Usual functions like LEFT,MID,RIGHT are available.
1-valiable Polynomial arithmetic:
ex. (1+_X)^2 is 1+2*_X+_X^2 use _X for the valiable.
Maximum loop time for FOR-NEXT is increased from 2^16-1
to 2^32-1.
