Fastest way to clear array

[Darrel Taylor]

what is the fastest way to clear an array without using "For ...next" loop?

CLEAR

But then, that clears everything.

The fastest way really depends on the PIC, and the array size.
Using FSR's will always be fastest.

But this one's really easy with PBP 2.60 (fast too).

ArraySize   CON 64
MyArray     VAR BYTE[ArraySize]

ARRAYWRITE  MyArray,[REP 0\ArraySize]

"Clear" means clear all variables in the RAM, or does it clear the register to the default state also eg TRISA, PORTB etc?

[Darrel Taylor]

Only the GP RAM, and all of it.
