TITLE MONRD PROGRAM TO READ WORDS FROM THE RUNNING MONITOR
;THIS PROGRAM IS USED TO TYPE OUT LOCATIONS IN THE MONITOR.
;IF THE LOCATIONS ARE IN THE JSB AREA OR PSB AREA, THE PROGRAM IS ABLE
;TO FIND THE PROPER DATA FOR ANY DESIRED FORK AND JOB NUMBER. TO DO
;THIS REQUIRES THE EXISTANCE OF A "MONRD" JSYS, WHICH IS INSERTED BY
;THE PROGRAM SYSDPY.

RET ;DONE
HLPTXT: TEXT <
This program is able to type words from the running monitor, whether
or not that data is in the resident monitor, swappable monitor, or
is in some fork's PSB or a job's JSB. Commands are:
CLEAR Zero the internal symbol table. This should only be
done if you have reason to think that the program's
symbol table is incorrect. Symbols are added to this
table whenever they are found.
CLOSE Close log file if one was in progress.
COLUMNS c1 ... Specify what kind of output is typed when showing a
location. The default is to show the address, the
value in octal, and the value in halfword symbols.
DEFINE s e1 Define the symbol s to have the value of the expression
e1. This is used only for ease in typing in of other
expressions. Typeout will never print the symbol.
FORK n Set which system-wide fork handle we are interested in.
This must be specified if locations in a PSB or JSB
are to be typed. A list of the forks for a job is
obtained by using the LIST command.
LIST n List all the system-wide fork handles of a job. The
output is ordered so that you can tell the fork
structure of the job.
LOG file Make a log file showing all valid commands and output.
MDDT Enter MDDT. MRETN$G will return.
SUPPRESS arg Specify that certain output is to be suppressed. Arg
can be one of the following:
COMMAND-ECHOING Don't show the command line in the
log file or to the terminal.
TTY-OUTPUT Don't type anything to the terminal.
An error will clear this.
ZERO-WORDS Don't type locations which are zero.
SYSTAT arg Do a systat of the indicated jobs. Arg can be any of
a job number, a user name, or just CRLF for all jobs.
TAKE file Take commands from the specified file.
TYPE e1 e2 Type out words from location e1 to location e2, where
e1 and e2 are expressions containing symbol names and
integers using the normal arithmetic operators. Typing
a ^E will abort the typeout.
UNSUPPRESS arg Undoes effects of the SUPPRESS command.
WATCH e1 n Continuously watch the contents of location e1,
typing it whenever it changes, sleeping n milliseconds
between checks. Typing a ^E will abort the watching.
VALUE e1 Find the value of the expression e1.
EXIT Leave the program.
HELP Type this message.
---------
Examples: 1. To type the JSYS stack for fork 0:
FORK 0
TYPE UPDL UPDL+NUPDL-1
2. To type the schedular tests for all forks:
TYPE FKSTAT FKSTAT+NFKS-1
3. To type the JFN block of JFN 3 for the current fork:
TYPE JFN0+3*MLJFN JFN0+4*MLJFN-1
4. To watch the process PC of the current fork:
WATCH PPC
Notes: There are some quantities which can be used in
expressions which are useful. These are the following:
'J The currently selected job number.
'F The currently selected fork number.
'E The value of the latest expression typed in.
'V The value of the location last typed out.
'R The right half of the location last typed out.
'L The left half of the location last typed out.
'A The address of the last location typed out.
Numbers in expressions are in octal, unless they contain
the digits 8 or 9 or are followed by a period, in which
case they are decimal.
