Hi.

Problem 1:

This line gives me "value out of range." error:

Code:

mov al, '\r'

I was pretty sure fasm would escape that and put the byte value. But I get that error. Does that really don't work as I expected?

----

Problem 2:

This gives me "undefined symbol 'AA55h'." error:

Code:

dw AA55h

But 1.2.4 Numerical expressions section says we can use h sufix.

If you want to use the CR character then type it like this:

Code:

mov al,13 ;ASCII CR

All numbers must start with a digit 0-9. When you have hex numbers then do this:

Code:

dw 0xaa55 ;0x prefix
dw 0aa55h ;h suffix

fasm never interprets the contents of strings for any reason. You get exactly what you type.

If you want a longer string with terminating characters then:

Code:

db 'Text string',0xd,0 ;CR and zero termination
