Displaying storage locations

To display storage locations, place the cursor on any yellow point-and-shoot address (for example, a register value), and press the Enter key. Alternatively, use the SHOW command (see SHOW for details).

An example of the storage display is shown in Sample Dump Storage display.

The character-interpreted section on the right-hand side of the hex data is generally displayed as EBCDIC. To instead display the data as ASCII, place the cursor on the ASCII point-and-shoot field and press Enter. With the cursor now on the EBCDIC point-and-shoot field, pressing Enter a second time reverts to the EBCDIC display.

Placing the cursor anywhere in the hexadecimal storage display area, and pressing the Enter key, takes you to the selected address. If the point-and-shoot field in which the cursor is placed is fewer than 8 digits, then it is padded with leading zeroes to form an 8-digit 31-bit address.

Overtyping the first two digits of an 8-digit address point-and-shoot field with zeroes, immediately prior to pressing the Enter key, ensures that the address is interpreted as a 24-bit address.

A 64-bit address is selected by overtyping the last digit of the point-and-shoot field which represent the first half of the 64-bit address (bits 0-31), or by overtyping the first digit of the point-and-shoot field which represent the second half of the 64-bit address (bits 32-63), before pressing Enter. This process logically 'joins' the point-and-shoot field closest to the underscore with the field in which it is placed. For example, given the following two adjacent address point-and-shoot fields

00000001 80109020

and either overtyping the last digit of the first field like this:

0000000_ 80109020

or the first digit of the second field like this:

00000001 _0109020

results in the 64-bit address 00000001_80109020 being displayed. As with 31-bit addresses, the second half of the 64-bit address is padded with leading zeroes to 8-digits.

A record is maintained of the last 10 addresses displayed. You can use the PREV (PF10) or NEXT (PF11) commands to redisplay areas previously selected.

The number of bytes per line shown depends on the visible width, not the current preferred formatting width. 32 bytes per line are shown if the visible width permits, otherwise 16 bytes are shown.

If available, a description of the initially selected address is provided, along with descriptions of the beginning of other storage areas, such as modules and programs, and any user notes (see Sample Dump Storage display).

Note that event numbers in descriptions that include these, such as Event 1 Program IDISCBL1 GPR 1 + X'1051' in Sample Dump Storage display, refer to event numbers in the Full event summary. If the Application Only setting is in effect for the event summary, event numbers might not match the storage descriptions. For additional information about the different event summary settings, see Primary option: Event Summary.

The FIND command used from this display behaves differently from that of all other displays, since it is the minidump which is searched instead of the formatted display itself. For details, see FIND command: differences between display types.

To display storage ahead of, or following, the storage in the current display, use the UP/DOWN commands as appropriate (usually mapped to PF7/PF8). Alternatively, an offset can be entered on the command line in the format:

Figure 2. Syntax

where hex-offset is a hexadecimal offset relative to the top left address shown. For example:

+10C

-D4
