Translation is the process of transforming all or part of a source program into a program image that contains all the information needed for the program to run.
Each nonempty sequence of white-space characters in a source program, other than the new-line character, is replaced by one space character. Comments are treated as white space. (2.1.1.2)
If you use the -C compiler option, comments are retained.
Diagnostic messages have the following format (2.1.1.3):
15cc-nnn (severity) text.
where:
cc Is a two-digit code indicating the compiler component that issued the message: 00 Code-generation or optimization message 01 Compiler services message 05 Front-end text message 06 Front-end error message nnn Is the message number severity Is a letter representing the severity level of the message text Is the message text describing the error
Diagnostic messages have the following severity levels:
| Letter | Severity | Compiler Response |
|---|---|---|
| I | Informational | Compilation continues. The message reports conditions found during compilation. |
| W | Warning | Compilation continues. The message reports valid, but possibly unintended, conditions. |
| E | Error | Compilation continues and object code is generated. Error conditions exist that the compiler can correct, but the program might not run correctly. |
| S | Severe error | Compilation continues, but object code is not generated. Error conditions exist that the compiler cannot correct. |
| U | Unrecoverable error | The compiler halts. An internal compiler error has been found. This message should be reported to your IBM service representative. |
The translator returns the following status codes for each severity level of diagnostic message:
| Message Severity | Return Code |
|---|---|
| Informational, Warning, or Error | 0 |
| Severe | 1 |
| Unrecoverable | 40 |
The level of diagnostic can be controlled with the following compiler options (2.1.1.3):
halt=severity
flag=severity1:severity2
