Message Severity Types

Every message displayed by ALP is assigned a specific type, and the type of message dictates the severity level. The following is a list of message types produced by ALP showing the type name (as it appears in the actual message), followed by a description of what caused the message, how severe it is, and the action taken by ALP after the message is generated.

Info

Informational message only; processing continues normally.
Warning
Questionable syntax or semantics; input file may be incorrect, but processing continues.
Error
Syntax or semantic error in input; continue processing, object output file is discarded.
Fatal
Unrecoverable user or environment error; terminate assembly prematurely after releasing resources and closing files.
Internal
Internal program logic error, abort immediately.
Usage
Incorrect command line syntax, abort.

When the assembler begins processing, the display of all warning messages is enabled; informational messages do not display unless they are requested. The display of both warning and informational messages may be controlled with the command line option M - Control Individual Messages or Groups See Message Control Options for more information on the behavior of assembler messages.
