Assembly error diagnostic messages

High Level Assembler prints most error messages in the listing immediately following the statements in error. It also prints the total number of flagged statements and their statement numbers in the Diagnostic Cross Reference and Assembler Summary section of the assembler listing.

The messages do not follow the statement in error when:

A typical error diagnostic message is:

** ASMA057E Undefined operation code - xxxxx

A copy of a segment of the statement in error, represented above by xxxxx, is inserted into many messages. Normally this segment begins at the bad character or term. For some errors, however, the segment might begin after the bad character or term. The segment might include part of the remarks field.

If a diagnostic message follows a statement generated by a macro definition, the following items might be appended to the error message:

Messages may reference three types of macro parameter: the name field parameter, keyword parameters, and positional parameters. A reference to the name field parameter is indicated by the word "NAME" appended to the message. References to keyword and positional parameters (for which there may be multiple occurrences) are in the form "KPARMnnnn" and "PPARMnnnn" respectively, where nnnn is the relative number of the parameter within the macro definition.

Figure 62 shows an example of a macro with messages referencing each type of variable or parameter.

If a diagnostic message follows a conditional assembly statement in the source program, the following items are appended to the error message:

Several messages might be issued for a single statement or even for a single error within a statement. This happens because each statement is usually evaluated on more than one level (for example, term level, expression level, and operand level) or by more than one phase of the assembler. Each level or phase can diagnose errors; therefore, most or all of the errors in the statement are flagged. Occasionally, duplicate error messages might occur. This is a normal result of the error-detection process.
