IFEQU @HL
Binary code : 00001111
Syntax : [< label> ] IFEQU @HL
Operation : (A) = M[(HL)]
Flags : CY : Unaffected
SF : Set to one if equal, cleared otherwise
Words/Cycles :
1/1
Description : Compares the contents of accumulator with the contents of data
memory addressed by registers H and L.
Example : LDA 14 ; Load 14 to A, and 14 must be decimal number
SETB H ; Sets H to one
LDL 4 ; Loads 4 to L
IFEQU @HL ; Compares 14 with M[(14)]
JMP 050 ; Jump to 050 if not equal
JMP 060 ; Jump to 060 if equal
I FEQU n
Binary code : 00001110 0111xxxx
Syntax : [< label> ] IFEQU n
Operation : (A) = n, n = 0 ~ 15 ( n must be decimal number )
Flags : CY: Unaffected
SF: Set to one if equal, cleared otherwise
Words/Cycles : 2/2
Description : Compares the contents of accumulator with an immediate data.
Example : IFEQU 15 ; Compare the contents of accumulator with 15
JMP 070 ; Jump to 070 if not equal
JMP 080 ; Jump to 080 if equal

Binary code : 00100010
Syntax : [< label> ] INC L
Operation : (L)
(L) + 1
Flags : CY : Unaffect SF:As a result of execution, set to one if the contents
of register L are zero, cleared otherwise.
Words/Cycles : 1/1
Description : The contents of register L are incremented by one.
Example : LDL 14 ; Load 14 to L
INC L ; The contents of L are incremented by one
INC L ; The contents of L are incremented by one
