[Amforth] how to use bitmask:

[Jan K. <jan...@ic...>]

Hello,

I need to do a  bitmask on register.

These are the constants, and mask

$24 constant ddrb
$25 constant portb

\ bit masks
%000100 constant mSS ( PB2 )
%100000 constant mSCK ( PB5 )

I wont 
1. to set the bits in ddrb with the bitmask mSS
2. to clear bits in portb with the bitmask mSCK

In bitnames.frt there is a word bitmask: How can I use it to do
the two actions above?

This is mor as a learning to understand working with bitmask.

Thanks for any help.

Jan
