Accessing Main Storage: CORE › The Structured Format › Use Another Program’s Data Definitions (USE Option) › The Dump Format

The Dump Format

The dump format is similar to a transaction dump printout, with a hexadecimal display area on the left and a character display area on the right. Obtain a dump format in the following ways:

• Use the Source Listing Breakpoint screen to display or modify a data item or area without a structure such as object code.
• Press Enter when completing a CORE menu or executing a CORE command.

The following display shows the dump format display of the CICS CSA (Common System Area).

Œ

Offset gives the hexadecimal displacement of the first byte of data on that line relative to the first byte of data on page number 0. Page number 0 is the first screen of a CORE display.



Hexadecimal display area shows each byte of data as two hexadecimal digits. Data is displayed 16 bytes per line, with spaces inserted after every four bytes (eight hexadecimal digits). The maximum size of a single CORE display is 17 lines, or 272 (hexadecimal 110) bytes of data.

Ž

Character display area gives the character representation for each displayable byte. Hexadecimal 40s display as spaces; non‑displayable bytes are indicated by periods. The columns of asterisks are not part of the data.



Address is the CICS hexadecimal address of the first byte of the line.



Task gives the task number of the breakpointed task for breakpoint‑related storage displays. For task‑related storage displays, gives the task number specified. (The default for task‑related storage is also the task number of the breakpointed task.)

‘

Page. Page numbers are relative to the initial screen display. Paging forward with PF8 increases the page count; paging backward with PF7 decreases the page count.

’

The area below the display area includes the following items:

• PF Key list.
• The command line in the Dump Format of CICS CSA displays the last CORE command entered or generated for the current display. To request a structured format of the current CORE display, press PF12. To request another CORE display or to enter a CNTL command, modify the command and press Enter (for a dump format or a CNTL command) or PF12 (for a structured format).
• The message line follows the command line and contains valuable information. Always read the message line on a CORE display.
• If CA InterTest for CICS could not locate a requested display area, the error message indicates that the requested area was not found. When this occurs, CA InterTest for CICS displays the dump format of the last or default CORE pointer location. The default area is the CSA.

Some messages can help you troubleshoot problems in storage.

Example

Whenever you are stopped at a breakpoint and request a COBOL storage display, CA InterTest for CICS automatically checks that the fields in the display contain valid data (according to their definitions). An error message tells you which fields are invalid and why.
