Pseudo instructions: if, endifIf you have only a single source file and you encounter only a few errors and you didn't enable additional fields in the list file then you can move the source into the trash, rename the list file and work on it as your new source file. You can easily find all the ***ERROR***s and correct them, then start over again. But be careful that the list file is not truncated before actually deleting it.
Assembler directives: #if, #elif, #else, #endif
Pseudo instructions: if, endifIf you suspect the assembler is generating wrong object code, you can include the object code in the listing. Then you can easily verify the generated code. Assembler directives: #if, #elif, #else, #endif
