Using a Compiler Listing

Using Additional-Diagnostic Messages

The Additional Diagnostic Messages section identifies errors which arise when one

or more lines of code are viewed collectively. These messages are not placed

within the code where the problem is; in general, the compiler does not know at the

time of checking that portion of the source that a problem exists. However, when

possible, the message line includes either the listing Line Number and SEU

| sequence number, or the Statement Number of a source line which is related to the

message.

Browsing a Compiler Listing Using SEU

The SEU Split/Browse session (F15) allows you to browse a compiler listing in the

output queue. You can review the results of a previous compilation while making

the required changes to your source code.

While browsing the compiler listing, you can scan for errors and correct those

source statements that have errors. To scan for errors, type F *ERR on the SEU

command line of the browse session. The line with the first (or next) error is high-

lighted, and the first-level text of the same message appears at the bottom of the

screen. You can see the second-level text by placing your cursor on the message

at the bottom and then pressing F1 (Help).

When possible, the error messages in the listing identify the SEU sequence number

of the line in error. The sequence number is found just before the message text.

Source Entry Utility

Correcting Run-time Errors

The source section of the listing is also useful for correcting run-time errors. Many

run-time error messages identify a statement number where the error in question

occurred.

| If OPTION(*NOSRCSTMT) is specified, the Line Number on the

left

side of the

compiler listing corresponds to the statement number in the run-time error

message. The source ID number and the SEU sequence number on the

right

side

of the compiler listing identify the source member and record. You can use the two

together, especially if you are editing the source using SEU, to determine which line

needs to be examined.

| If OPTION(*SRCSTMT) is specified, the Statement Number on the

right

side of the

| compiler listing corresponds to the statement number in the run-time error

| message. If the statement is from the main source member, this is the same as the

| statement on the

left

side of the compiler listing, and is also the same as the SEU

| sequence number.

If you have a /COPY member, you can find the source ID number of the actual file

in the /COPY Member table at the end of the listing. For an example of a /COPY

Member table, see “/COPY Member Table” on page 432.
