Some aspects of implementation

If you use the jump label (where to go) before specifying this jump location, then DOUBLE ASSEMBLY will be done. Because during the assembly process, a list of all the labels in the code is compiled.

That is, when reassembling, the missing arguments of the transition commands will be substituted.

Use the label where to jump like:
NAME_OF_LABEL :
When displaying an image on the screen, it is allowed to recolor the shaded pixels.
Description of all procedures is allowed only after the entire program. If another procedure is called from an executable procedure, then they must be placed in a hierarchical order.

Сalling scheme: proc_1 --> proc_2 --> proc_3

Code scheme:
proc_1
proc_2
proc_3

Commands

`PUSH` - put it on the stack

NUMBER: PUSH 2
REGISTER: PUSH AX
PUSH FROM THE ADDRESS: PUSH [2] PUSH [AX]

`POP`- get it from the stack

REGISTER: POP AX
POP TO THE ADDRESS: POP [2] POP [AX]

`CALL` - call the procedure

`OUT` - finish the procedure, go back

JUMPS

JMP — unconditional
JA — >
JB — <
JAL — >=
JBL — <=
JE — ==
JNL — !=

`PVM` - put in the video memory segment

Arguments: { X Y R G B }
Example: PVM 10 1 255 100 0

X Y - position of pixel
R G B - Red Green Blue ( range is [0, 255] )

`SHOW` - display the entire segment of video memory

`RET` - the end of asm program (there may be several)

`HLT` - the logical end of the program

the processor stops executing
you are required to use at the end of the program
