Use DUMP to produce a system dump at compile time for an internal compiler error.

DUMP option syntax

Default is: NODUMP

Abbreviations are: DU|NODU

Not for general use:
The DUMP option should be used only at the request of an IBM representative.

The dump, which consists of a listing of the compiler's registers and a storage dump, is intended primarily for diagnostic personnel for determining errors in the compiler.

If you use the DUMP option, include a DD statement at compile time to define SYSABEND, SYSUDUMP, or SYSMDUMP.

With DUMP, the compiler will not issue a diagnostic message before abnormal termination processing.
Instead, a user abend will be issued with an IGYppnnnn message.
In general, a message IGYppnnnn corresponds to a compile-time user abend nnnn.
However, both IGYpp5nnn and IGYpp1nnn messages produce a user abend of 1nnn.
You can usually distinguish whether the message is really a 5nnn or a 1nnn by recompiling with the NODUMP option.

Use NODUMP if you want normal termination processing, including:

• Diagnostic messages produced so far in compilation.
• A description of the error.
• The name of the compiler phase currently executing.
• The line number of the COBOL statement being processed when the error was found.
  (If you compiled with OPTIMIZE, the line number might not always be correct; for some errors, it will be the last line in the program.)
• The contents of the general purpose registers.

Using the DUMP and OPTIMIZE compiler options together could cause the compiler to produce a system dump instead of the following optimizer message:

This situation does not represent a compiler error.
Using the NODUMP option will allow the compiler to issue message IGYOP3124-W and continue processing.
