assembly - What is wrong with this line of Lc3 code? -


i doing practice exam question.

the question is

is there wrong in line of lc3 code? (the starred line)

add r3, r3, 0; **brnz ispos;** halt .blkw 250 ispos not r3, r3 ....

i saw starred line branch , condition codes negative , zero, go label ispos if condition code negative or 0 or halt program otherwise.

i line of lc3 code has nothing wrong it. see problems it?

yes, there couple different errors code segment.

opcodes cannot have other label preceding them. 

**brnz ispos;**

must become:

brnz ispos;**

you cannot have random characters after operands, unless commented out

ispos not r3, r3 ....

must change to:

ispos not r3, r3 ;....
