Re: V-FORTH - Forth-83 for the VIC

hello, good day.

my test text for forth gives an error message.
I transferred the text to a dsk.d64.

when I load the file with "include test.fs"
the error message appears.

your other fs work.
they are on the same disk.

where is the error.

thanks.

Re: Accumulator Addressing

Hi good afternoon.

The assembler instruction LSR shifts the eight bits of the accumulator one place to the right and not 2...3...4..

ok is :
LDA #$10
LSR



or 3 Bits:
LDA #$10
LSR
LDA #$10
LSR
LDA #$10
LSR
