|Description||Jump if A positive or zero|
|Affected||If A>=0 P:=P+Δ|
JAP is an assembly instruction. If the A register is positive or zero (bit 15 = 0), it jumps the program execution to the address of the program counter (P register) plus the value of displacement which can be between -128 to 127. Else it continues the program execution at (P) + 1.
