KDCDUMP statements

The following table gives an overview of all the KDCDUMP statements and their meanings:

Statement	Meaning

!!	Execute most recently executed system command again
AFIND	Find address in UTM dump
scrolling statements	Position cursor in work area
DUMP	Read complete UTM dump or part of a UTM dump into memory
EDT	Call editor
END	Terminate KDCDUMP
FIND	Find and show table entry
FGG	Edit all files of an FGG (file generation group)
FILE	Edit single dump file
HELP	Display help for KDCDUMP statements
LIST	Edit table section
REPFILE	Information about REP file (only BS2000 systems)
SFIND	Search for a pattern in the dump
SH | SYS	Start a Bourne shell from KDCDUMP on Unix and Linux systems or open a command prompt window under Windows systems (cmd.exe).
SYSLST	Activate/deactivate logging
TABLE	Show table

Entering KDCDUMP statements

KDCDUMP statements are read from stdin. A statement may comprise up to 256 characters; longer inputs result in error message K759.

Where statement names can be abbreviated, this is indicated in bold type. Thus, for example AFIND, indicates that you can abbreviate the statement name to AF.

With certain operands, one of the three input formats "C-string", "X-string" or "decimal" must be observed:

Designation	Input format / Example
C-string	[C]'This is a C-string'
X-string (hexadecimal)	X'AAAF' or X'aaaf' or X'AaAf'
Decimal	12345

If indices or displacements/offsets are specified, then these are always interpreted as being positive.

Note for openUTM on Unix, Linux and Windows systems on Intel processors

Hexadecimal inputs are always interpreted as arithmetic, i.e. indices or displacements which are read directly from the hexadecimal edited dump must be entered byte for byte in the reverse order, i.e. as arithmetic, for "little endian" machines (e.g. Intel). Generally, it is unnecessary to enter leading zeros.

Little endian examples

1. The  4-byte  displacement  X'00010203'  is edited as X'03020100'  in thehexadecimal section  and  must be entered as X'00010203'.

2. The  2-byte  index X'FEAF' is edited as X'AFFE' in the hexadecimal section  and  must be entered as X'FEAF'.

In the following, "output to terminal" signifies the output to stderr.

The sections which follow describe the KDCDUMP statements in alphabetical order. Only the statements and operands are described here which are used for evaluating the KDCROOT area (see chapter "The KDCROOT area").
