Hi guys, it's that Polack from NY with another dumb syntax question.

The Micromite Manual.pdf says

  Quote  

TIMER Returns the elapsed time in milliseconds (eg, 1/1000 of a second) since reset. The timer is reset to zero on power up or a CPU restart and you can also
reset by using TIMER as a command. If not specifically reset it will continue to count up forever (it is a 64 bit number and will only roll over to zero after 200 million years).

200 million years is 6.3072E+18 ms.
A 64 bit binary could count to 1.8447E+19 ms.

But the MMBasic Language Manual.pdf says

  Quote  

TIMER CMM MM DOS Returns the elapsed time in milliseconds (eg, 1/1000 of a second) since reset. If not specifically reset this count will wrap around to zero after 49 days. The timer is reset to zero on power up and you can also reset by using
TIMER as a command.

49 days is 4.2336E+09 ms.
A 32 bit binary could count to 4.2950E+09 ms.

Which seems to indicate that it was changed from 64 bits to 32 bits sometime.

The Micromite Plus manual is silent on the matter.

So, which version of MMBasic and which chips use 64 bits and which use 32 bits?

Paul

The colour maximite V4.5 uses 32 bit. Al numbers are floating piont so while the internal counter rolls over every 49 days, the usable count is less and you would need to do your own overflow code.

The later micromites had 64 bit integers added to the mix. This makes life easier.
