Example: Assembler code generated from source code
The following example shows a listing of the assembler
code that is generated from source code when you use the LIST compiler
option. You can use this listing to find the COBOL statement that
corresponds to the instruction that failed.

- (1)
- Source code interspersed with the pseudo-assembler instructions
- (2)
- Relative location of the object code instruction in the module, in hexadecimal notation
- (3)
- Object code instructions, in hexadecimal notation
The first two or four hexadecimal digits are the instruction, and the remaining digits are the instruction operands. Some instructions have two operands.
- (4)
- Source line number associated with this assembler code
- (5)
- Object code instructions, in compiler-generated pseudo assembler
- (6)
- Explanation of the instruction and the operands used by the instructions
