XXa valid mailbox address between 0 and 99YYYa valid mnemonic/instructionZZ(Optional)only for instructions requiring data.(Optional)required for indirect addressing mode.There should be ';' in aline if it has some text.Every thing after a ';'is considered as a comment.You can have any numberof blank lines in your source code.After typing your sourceprogram, you can hit 'Get Opcode' to get the opcodes for the instructions you have typed.The application checks for syntax at this time and displays the error message in theProgram Status Field. It also highlights the instruction containing the error.ExecutingProgramIn order to execute theprogram, you will have to load the source program into the mailboxes first.

Once you getthe opcodes for the source program you have entered, click on 'Load' to load theprogram into the specified mailboxes. After this step, you can execute the program in oneof the three ways:.Execute - This willexecute the source program in burst mode.Step Into - This willexecute one instruction at a time.Step Over - This willexecute one instruction at a time except for skip instruction. For skip instruction, itwill execute the next instruction if the condition mentioned in the instruction issatisfied.The program status fielddisplays the status of the program and the instruction executed.

In this challenge we will create a computer program using LMC (Little Man Computer) that takes a number as an input (e.g. 5) and outputs a countdown from this value. (e.g: 5.4.3.2.1.0).By completing this challenge we will investigate the use of the branching instruction BRP to create a l ooping effect.FlowchartWe have produced the flowchart of our countdown timer using LMC instructions:LMC SimulatorsYou can now type and test this code using one of the following online LMC Simulators:.LMC Instruction SetNote that in the following table “xx” refers to a memory address (aka mailbox) in the RAM. The online LMC simulator has 100 different mailboxes in the RAM ranging from 00 to 99.
Use two or more programming languages, at least one of which is textual. The Little Man Computer (LMC) is a simulator which models the basic. The LMC can be programmed using either 'Machine Code' or 'Assembly Language'.
