The HDR command analyzes the disk file header stack or a particular header and prints out that analysis.

Explanation
The following text describes the meaning of each construct. Refer to “Basic Constructs” earlier in this section for information about the <number> and the <quoted file title> constructs.
HDR
Prints an analysis of all the file headers that existed in memory when the dump was performed. Row address words are not printed.
HDR ATTRIBUTES
Prints a list of file attributes for all of the file headers that existed in memory when the dump was performed.
HDR SUMMARY
Prints a list containing the location and names of all the headers that existed in memory when the dump was performed.
HDR ROWS
Prints all the information that the HDR form produces plus an analysis of the row address words.
HDR <number>
Prints the same information as HDR, but only for the header specified by the number.
HDR <number> ATTRIBUTES
Prints a list of file attributes for the header specified by number.
HDR <number> ROWS
Prints the same information as HDR ROWS, but only for the header specified by the number.
HDR <number> RAW
Prints in hex format the entire header specified by the number.
HDR <quoted file title>
Analyzes every disk header whose title matches the file title.
HDR <quoted file title>ATTRIBUTES
Prints a list of file attributes for every disk header whose title matches the file title.
HDR <quoted wild-card string>
Analyzes every disk header whose title matches the sequence of characters specified in the quoted wild-card string. The wild-card characters include the equal sign (=) and the question mark (?).
-
The equal sign matches any sequence of characters.
-
The question mark matches any single character.
Enclose the wild-card string in either apostrophes (') or quotation marks ("). Use apostrophes if the required file title contains special characters that are enclosed in quotation marks.
Following are some examples of the HDR <quoted wild-card string> command:
|
The command . . . |
Analyzes every disk file header . . . |
|
HDR "=CFILE=" |
With the string CFILE in the file title. |
|
HDR '=s/sc=' |
With the string s/sc in the disk file title. |
|
HDR "=P?X=" |
That contains the letter P, followed by any single character, followed by the letter X anywhere in the file title. |
HDR <quoted wild-card string> ATTRIBUTES
Prints a list of file attributes for every disk header whose title matches the sequence of characters specified in the quoted wild-card string.
HDR <quoted file title> ROWS
HDR <quoted wild-card string> ROWS
Prints the same information as the HDR ROWS command, but only for the header specified by the quoted file title or the quoted wild-card string.
HDR <quoted file title> RAW
HDR <quoted wild-card string> RAW
Produces a printout in hex format of the entire header specified by the quoted file title or the quoted wild-card string.
HDR JOB <decimal number>
Searches the header stack and prints the requested header if it is located.
HDR JOB <decimal number> ATTRIBUTES
Prints a list of file attributes for the header associated with the specified job.
HDR JOB <decimal number> ROWS
Prints the same information as the HDR ROWS command, but only for the header specified by the job number.
HDR JOB <decimal number> RAW
Produces a printout in hex format of the entire header specified by the job number.
Example 1
The following example shows output from the HDR command. The following list explains the various lines of the output in the example:
-
The first line with HDR [number] on it shows the data descriptor for the array containing the disk file header, and it shows the title of the file.
-
The line with HDR0 [number] on it shows the word in the MCP HDR0 array that the system uses when it searches to determine whether a particular file has a header in memory.
-
Optionally, a line that contains HEADER LOCK shows the stack that owns the lock for the header. The MCP uses this lock when it alters the header. DUMPANALYZER prints this line only if the lock is owned by a stack.
-
Next is a detailed display of the words in the header, the row address words for the header (if requested with the ROWS option), and the OPTIONAL ATTRIBUTE WORDS contained in the header.
-
The line that contains MEMHDRS [number] on it shows the descriptor for the array that the MCP uses to keep track of the header while it is in memory.
-
Last is the detailed display of the words contained in the MEMHDR for that disk file header.
