Hi, guy's I took a test today and I got wrong answer. can you gyus tell me why? I chose true.

[HTML]True or False. Given that CL and DL contain SIGNED numbers the code fragment below correctly implements the following pseudocode.

Pseudocode: If (CL < DL) then
Call less

Code Fragment: CMP CL, DL
JAE @@COMMON
CALL LESS
@@COMMON
{RAP}

a.) True
b.) False
[/HTML]

Thank you.

JAE is used to deal with signed numbers. I think what you need is JGE

Other way around. JAE is for unsigned values, JGE is for signed values.

nop, JAE is just a conditional branching only jump of is above or equal. You can use JAE with signed or unsigned numbers.

You might be able to "use" it but it might not work the way you intend it to

Yep you can use it with Byte Word or DWord, with 16-bit real mode or 32-bit protected mode, Thanks for traying.
