A register in computer science refers to a section of RAM used to store and operate on their values.
There are several registers, such as the A, B, C, D, E, F, H, and L registers, although, the names of these may very depending on the processor and the assembler.
All of these registers mentioned are 8bit registers. Meaning, they can only hold 1 byte of data, ranging from 0 to 255.
In order to achieve more memory, you can combine two registers. For example, the "HL" register refers to a combination of the "H" and "L" registers which create a 16bit, or 2 byte, section of RAM for storing data.
So, in conclusion, the HL register is a 16bit section of RAM in which you can store two bytes of data and operate on their values.
The h-L register in computing refers to a pair of registers used in some processors to store a 16-bit memory address. It is often used for memory operations and calculations involving memory addresses. The h register stores the high-order byte while the l register stores the low-order byte of the address.
The past tense of "register" is "registered."
The five registers in ASL are: everyday or casual register, frozen or highly formal register, formal register, consultative register, and intimate or informal register. Each register is used in different social contexts and requires varying levels of fluency and cultural understanding.
The preposition "for" typically comes after the verb "register." For example, "She registered for the class."
to register : enregistrer (one's luggage at the airport, ...) or s'enregistrer (suscribe on a website, ...)

HL is a general purpose 16 bit register. It is also the address in memory of the M register.
Because in many statements you use HL as a pointer to memory data, eg: LD B,(HL) SUB A,(HL) LD (HL),E
HL is a register pair used to store 16 bit of data in 8085 microprocessor.
An indirect address is an address contained in a register or memory location, instead of in the instruction itself. In the 8085, the most common form is to load or calculate an address in the HL register, and then access the memory pointed to by HL using the M register designation, such as MOV A,M.
MOV D,reg means: move content of the specified register (or M=memory addressed with HL) into register D
hl pair holds the address of the location pointed by the memory pointer M
The various 16-bit registers on the 8085 are BC, DE, HL, SP, PC.
HL is a register pair that is used to store 16-bit data in 8085 Microprocessor
It is register addressing mode, as it moves the content of HL to PC which is data and not address.
XTHL instruction exchanges the contents of H-L register pair with the contents of the stack pointer (SP). SPHL instruction loads the HL register pair with the address contained in the stack pointer (SP), where SPHL = HL ← SP.
Because that is the way Intel designed the INX instruction of the 8085. The 8080 is also the same. INX increments (and DCX decrements) the 16 bit register pairs or BC, DE or HL, depending on what register pair you specify in the INX (or DCX) instruction. To check is the value is 0 after an INX (or DCX) instruction, you need to OR the values of the register pair into the A register. For example..... INX H ;increment HL register pair MOV A,H ; move H register into the accumulator ORA L ; Logical OR it with the L register JZ ADDR ; If 0 then jump to ADDR
