Positive negative asm tests



I was looking at Greg Parker's (I think) zshell/asm lessons and in it it
says.
ld a,number_to_check_if_positive_or_negative
JUMP_P(aispositive) ;it says these will work?
JUMP_N(aisnegative) ;Is this true, I have never seen this used before

Please, if those are legal please tell me, they would be very useful!!
