Assembly and Output
Description:
Resolving symbolic addresses (labels) and generating machine language is a crucial step in the compilation process of a PL/I program. This process involves converting the high-level code written in PL/I into machine-readable instructions that can be executed by the computer.
Assembly:
During the assembly phase of compilation, the compiler translates the symbolic addresses (labels) used in the source code into actual memory addresses where the instructions or data are located. This process is essential for the program to be able to access the correct memory locations during execution.
Output:
Once the symbolic addresses have been resolved, the compiler proceeds to generate the actual machine language instructions that correspond to the PL/I code. These machine language instructions are specific to the target architecture for which the program is being compiled.
Significance:
The assembly and output phase is critical as it is responsible for producing the final executable code that can be run on the target machine. Without this step, the program would not be able to be executed as intended.
By resolving symbolic addresses and generating machine language, the compiler ensures that the PL/I program is translated into a format that the computer can understand and execute efficiently.
