data error

[zev]

In section.data, the line: number db 7 dup 0 gives the error message:comma expected after operand 1. But, there is no operand. Why the error message?

Nasm doesn't know "dup" - that's Masm/Tasm/Jwasm syntax. Try:

Code: [Select]

number times 7 db 0
Should give you the same effect.

you could and should put uninitialized data in the .bss section and do it this way:

Code: [Select]

section .bss
number    resb 7

I'm afraid I don't understand your point here. Zed did initialize the data. That's why he was using the MASM directive dup(0) instead of dup(?).
