UBASIC is a marvellous BASIC-like system using high-precision arithmetic, written by Prof. Yuji Kida of Japan.
However, the date function produces CCYY for the year where CC is the century but YY is the 2-digit year with a leading blank!
For example, in 2009 we saw:
Words for long variables 540 (Words for internal calculation 540)
Free text area = 39655 bytes
20 9/12/30/ 9:22:08
But finally, in 2010, it is now fixed:
2010/ 1/25/ 0:19:55
And it only took 10 years! 🙂
