COMMENT ⊗
For FAIL and Macro programs the calling sequence is:
EXTERN SPOOLM,SPL%CN
PUSHJ 17,SPOOLM
JUMP ARGS
where ARGS is the address of a four word lookup block that has the
appropriate flags in the right half of ARGS+1. The IO channel that is
used may be selected by setting the external variable SPL%CN to some
number which will be used (mod 20 octal) as the channel number to
use. The default is channel 17. The address of ARGS may be anywhere
in your core, except that if you use the accumulators for ARGS, then
ARGS must be smaller than 14 so that all four words will fit beneath
17. As a programming convenience, all accumulators will be restored
by this routine to their original values.
All programs:
The flags have the following significance:
Octal Bit Meaning
1 (bit 35) delete this file after listing
2 (bit 34) do fortran carriage control
4 (bit 33) use LPT mode 101 instead of mode 1.
10 (bit 32) delete SOS line numbers
20 (bit 31) print headings at the top of each page
40 (bit 30) suppress the title page.
100 (bit 29) make narrow title page for 8.5" paper
200 (bit 28) list data as octal words.
400 (bit 27) suppress message announcing "spooling done"
1000 (bit 26) convert all line feeds to '177&'21.

You are using Dired, a program that displays a directory of your
choosing, and permits you to modify it in various ways. Files may be deleted,
edited, or renamed (soon) using Dired.
In command descriptions below α and β are used to mean Control and Meta
respectively. Most commands take prefix arguments. Type arguments while
holding the Control and Meta keys. eg. αβ-αβ6αβ9 is an argument of -69.
These are the command for moving around in the display:
CR Move down one line BS Move up one line
αβ< Move down 1/8th screen αβ> Move up 1/8th screen
αβ≤ Move down 1/2 screen αβ≥ Move up 1/2 screen
αβW Down to next screenful αβL Up to next screenful
αβT Move to the top line αβB Move to bottom line
αβJ Jump current line top top
Here are the rest of the commands with brief descriptions:
αβD Delete a file αβE Exit the Directory Editor
αβM Reads a file mask [ Reads a PPN
αβV Redraws the screen /HELP Displays switch documentation
/EDIT Enters E on the current file
/EXAMINE Enters E on the current file in /R mode.
- - - - - - - - - - - - - - - - - - - - - - - - - - - ¬
You may return to Dired from E by typing αXDI<RETURN>
More information is available in DIRED.SGK[UP,DOC]
Type αβV to get back to your files

SGEN [ASCIZ ≡
You are in Delete List mode. Enter it and leave it with the /SHOW
command. The files shown here are ones which you have told Dired to
delete. Files can be removed from this list by using the αβD command
in th same way you used it to get them here.
In command descriptions below α and β are used to mean Control and Meta
respectively. Most commands take prefix arguments. Type arguments while

Here are some other commands:
αβM Reads a file mask [ Reads a PPN
αβV Redraws the screen αβD Deletes entries from the delete list
/ Reads at least one switch (any number may be given)
/HELP Displays documentation on the switches

/F or FAST Puts you in fast mode. No lookups are done when reading UFD's.
/FULL MODE Removes you from /F mode. Displays dates, times, sizes, etc. of files.
/HELP Displays this cruft.

/OUTPUT Writes all the directory information on the filename given.
/REVERSE Displays the files in reverse order. Sticky over other sort commands.
/SHOW Switches display modes between delete list mode and the normal mode.
/SIZE SORT Sorts the files by size.
