You just have the knack of finding out all these weird issues.

Does it also count that in hisoft basic, the classic "X,Y" order is actually "Y,X"... that drove me nuts as well :roll:

Probably last update for the week..

Adding in a new option to set the ST's time & date from the RTC clock... "almost" works :lol:

Really I need someone to do a simple version in ASM which can access the RTC registers and set the ST's clock.. like a small AUTO folder program..

EDIT:

Fixed the date bug.. but no matter what I put in as the year, it always reads (from the ST) "20;9"... I tried putting in "2019", "20", "19" but makes no odds.... I'm assuming the internal ST clock just doesn't work with these numbers :shrug:

I tried using the TSETDATE function and it worked in that I could set 1/1/1980, but again setting 2019 resulted in "20;9" :roll: So its not a bug in hisoft in setting the date.. so maybe reading the date is wrong.. will try a system call for that next...

EDIT:

The value I write to the ST clock comes back the same, so I think its a bug in reading the time in hisoft basic :roll:
