EXAMINE
%SDA-E-NOINSTRAN, cannot translate instruction
When you use this qualifier with the EXAMINE command, SDA calculates
subsequent default addresses by adding the length of the last instruction,
including all operands, to the last address examined.
/NOSKIP
Causes the EXAMINE command not to skip any bytes in the range when
translating the contents of memory into MACRO instructions. The /NOSKIP
qualifier causes the execution of the /INSTRUCTION qualifier by default.
/NOSUPPRESS
Inhibits the suppression of zeros when displaying memory with one of the
following qualifiers: /ALL, /P0, /P1, /SYSTEM.
/P0
Displays the entire program region for the default process. Do not specify
parameters when you use this qualifier.
/P1
Displays the entire control region for the default process. Do not specify
parameters when you use this qualifier.
/PSL
Examines the specified longword, displaying its contents in the format of a
processor status longword. This qualifier must precede any parameters used in
the command line.
/PTE
Interprets and displays the specified longword as a page table entry (PTE). The
display separates individual fields of the PTE and provides an overall description
of the PTE’s type.
/SYSTEM
Displays portions of the writable system region. Do not specify parameters when
you use this qualifier.
/TIME
Examines the specified quadword, displaying its contents in the format of a
system-date-and-time quadword.
Description
The following sections describe how to use the EXAMINE command.
Examining Locations
When you use the EXAMINE command to look at a location, SDA displays the
location in symbolic notation (symbolic name plus offset), if possible, and its
contents in hexadecimal and ASCII formats:
SDA> EXAMINE G6605C0
806605C0: 80002119 ".!.."
If the ASCII character that corresponds to the value contained in a byte is not
printable, SDA displays a period (.). If the specified location does not exist in
memory, SDA displays this message:
%SDA-E-NOTINPHYS, address : not in physical memory
SDA–54
