40 labels in assembly language examples

What Is Assembly Language? (With Components and Example) In this example of an assembly language, "1:" is the label which lets the computer know where to begin the operation. The "MOV" is the mnemonic command to move the number "3" into a part of the computer processor, which can function as a variable. "EAX," "EBX" and "ECX" are the variables. The first line of code loads "3" into the register "eax." Local Labels - Elements of Assembly Language - 123dok Here are some examples of legal identifiers: Grab Hold Widget Pot_of_Message MAXNAME A numeric label consists of a digit (0 to 9) followed by a colon. As in the case of alphanumeric labels, a numeric label assigns the current value of the location counter to the symbol.

Learning Assembly Language | Codementor Typically examples are telling the assembler that the following instructions are code (usually via a .text directive) vs. data (usually via a .data directive). Like regular instructions, these instructions are typically written on their own line, however, the inform the assembler rather than generate machine code instructions directly.
