Error Messages
All errors recognized by the Ax51 Assembler are output to the listing file. Two classes of errors exist: fatal and non-fatal.
Fatal Errors indicate an unrecoverable problem and cause the assembler to immediately halt. These types of errors are usually caused by a disk problem or access problem.
Non-Fatal Errors do not halt assembly but may indicate a problem that prevents correct or valid assembler output. These types of errors are typically caused by syntax or semantic errors in the source file.
