$parscl
#'Parscl' did not bother to set the end-of-buffer pointer on exit,

$pg
#Removed  internal  pagination routine, replaced it with a call to

$fcopy
#Double  bug  fix:  First, 'fcopy' was not calling 'mapsu' on file

#Completely  rewritten.   Now  has "level numbers" on options that
#will hopefully allow the user to remember  what  few  options  he
#really needs.  Does extensive checking on options to avoid upset-
#ting  FTN.   Uses new file name syntax to be more compatible with
#the rest of the Subsystem.  Produces an FTN command that does not
#depend on having funits 1-3 already open.  FTN  command  produced
#uses command-line options rather than register settings.

$parscl
#Modified parscl so that

$find
#Rewritten to use 'parscl' and 'gfnarg' to parse the command line.

$fsize and related modules
#The  code  has  been  re-organized to be a bit easier to read and
#(hopefully) a bit more efficient.
#
#Note that fsize returns a value of 2 records when asked to size a
#totally empty DAM file; this is actually the correct  value  (see
#//pri400/ks/newfil).
#
#The  "-f"  option  now  forces  a read/write lock value of n+1 if
#needed.  This is in addition to the forcing of r/ protection,  if
#needed.  To avoid some potentially messy problems if someone were
#to  "break" about these calls, fsize (and the routine fsize$) now
#disable the break until the file is  set  back  to  its  original
#levels.   Note  that  since we cannot obtain the transaction lock
#except in ring 0, it is entirely possible that someone else could
#grab the file too.  Therefore, DDDOOO  NNNOOOTTT  use  fsize  on  files  or
#directories that depend on the read/write lock as a critical lock
#or you will possibly cause problems.
#
#The  documentation  has  not  yet  been  updated  to reflect this
#change.
!Wednesday, 08/20/80 22:46:49
*Gene
$fsize and related subroutines and functions
#The  "-s"  option  has  been  removed.   The  command now calls a
#special routine which checks the "funny bits" in the rden$$ entry
#for the dskrat of the mfd of the target disk.   The  record  size
#may  be directly calculated from the presence or absence of a bit
#there.  As a result, pathnames to different disks may  be  freely
#mixed  in  each  invocation of the command.  Note that the mfd of
#all disks must be able to be  attached  to  with  a  password  of
#"XXXXXX" for non-privileged users...

#The  manual  entry  has  been  updated to reflect the options and
#operation as of this date.

*Perry
$xref
#Modified  error  message  code to produce more readable messages;
#"can't open include" message now gives the name  of  the  include
#file  that  can't  be  opened; "includes nested too deeply" is no
#longer fatal.

#Modified sort code for greater speed and  to  collate  upper  and
#lower case alphabetics together (i.e., 'a' < 'A' < 'b' ...).
!Sunday, 08/24/80 18:51:04
*Perry
$open, dopen$
#Added an optional parameter to allow the specification of a retry
#count  when  opening a disk file.  If the retry count is non-zero
#and the file is already in use, 'dopen$' waits for 1/2 second and
#then trys again to open it.  This is repeated until the  file  is
#opened   successfully  or  the  specified  number  of  retrys  is
#exhausted.  If a retry count of -1 is specified, an infinite num-
#ber of retrys is assumed; if the retry count  is  omitted,  0  is
#assumed.

$fmt
#Fixed the following bugs:
#
#     The  text  produced  by  a  'tl'  command was subject to the
#indentation value then in effect, in conflict with  the  behavior
#described in the documentation.
#
#     The  text  of headings and footings always began immediately
#after the page and margin offsets and did not take  into  account
#the current left margin as described in the documentation.

$parscl
#An <opt int> keyletter that appeared in other than the last posi-
#tion  of an argument string and whose integer parameter was omit-
#ted was being marked as  having  an  integer  parameter  present.

#
#An <opt int> or <req int> keyletter would not accept  a  negative
#integer  parameter  when  the integer was specified as a separate
#argument, even though it would if the integer  was  part  of  the
#same argument string.  The code that used to check only the first
#character  of  the  parameter string for "digitness" now augments
#that check with one that detects a leading minus sign followed by
#a digit.

$vars
#Corrected  the  operation  of  the  "-l" option to conform to the
#documentation.  Corrected a typographical error in the usage mes-
#sage.

$=src=/lib/swt/src/date.r
#Modified  the main select statement to use the symbolic constants
#(SYS_?)  from the standard definition file  instead  of  explicit
#numbers.  Removed the last entry from the string table containing
#the  names of the days of the week and altered the encode formats
#that used it (SYS_DAY and SYS_LDATE).

$crypt
#Added  code to prompt for the encryption/decryption key with echo
#disabled when not supplied as an argument.

$fsize
#Fixed the bug in fsize that caused it to return an incorrect size
#for  files  that were open when using the "-f" option.  Corrected
#version has been installed on GT.A,  GT.B,  GT.C,  and  corrected
#source installed in =src=/std.r on GT.C only.

$lps
#Fixed a bug that made it impossible to cancel a queue entry for a
#print  file  that had already been deleted.  Changed the "prtxxx:
#printing"  message  to  "prtxxx:   in  use"  to  more  accurately
#describe the condition that causes the message to be issued.
!Saturday, 11/22/80 13:47:06
*Gene
$fsize
#Yet  another  fix....this  time  fixed  fsize  so  it returns the
#correct size for boot files and any other files that have special
#bits set in the high order byte of "file_type" (value returned in
#SRCH$$ and RDEN$$).  Hopefully, the last fix....
#
#Corrected source is on system C.  Corrected executable code is on
#systems A, B, and C.

$sh
#Changed  command  statistics  recording  so it is controlled by a
#template rather than a compile-time option.

$as11
#Several  local  improvements  to  symbol table handling, I/O, and
#lexical analysis.  Improved speed by over 70%.

$st$lu
#Fixed  bug  in hashing algorithm that allowed a negative value to
#be passed to the Fortran MOD intrinsic, thus calculating a  bogus
#hash table index.
!Friday, 11/28/80 12:57:53
*Dan
$swt_com.s.i, swt_com.r.i
#Added  fields  for  terminal type, newline character, and end-of-

#octal as their ASCII value.
!Wednesday, 12/03/80 17:22:12
*Gene
$fixp
#Fixed a bug in the blank compression logic.

$wkday
#Use  of  the Fortran mod function caused the occasional return of
#values -6 through 0, instead of 1 through 7, respectively.

*Dan
$edit
#Corrected  longstanding bug in 'gtxt'.  When passed "line0" as an
#argument, 'gtxt' wrote a NEWLINE into txt (0).  Up  until  "Fdin"
#and  "Fdout"  were  added to the common blocks, this overwote the
#last character of "savfil", causing no detectable  damage.   Once
#"Fdout"  appeared in the common block, this bug caused the output
#file descriptor to be overwritten with a NEWLINE whenever "line0"
#text was referenced.
!Wednesday, 12/24/80 13:50:32
*Dan
$sh
#Modified  'file_type'  in 'sh_exec' to return BINARY_FTYPE in the
#case of segment directories and file  directories.   This  allows
#the modifications for executing segment directories to work.
!Wednesday, 12/24/80 13:51:55
*Dan
$pc
#Modified  the "build" procedure so that 'pc' is no longer shared;
#it resides in a segment directory that can be executed  from  the
#Subsystem.  The "build" procedure can also build a shared version
#as before.  .

$uniq
#'Equal'  was not declared as an integer function, causing strange
#results.  Question:  For a program that's been working  for  four
#years, how did this come about?
!Friday, 12/26/80 15:06:45
*Dan
$swt
#Fixed  bug  that  cause  the  main  program of 'swt' to return to
#'init_stack' when the variables file existed, but  could  not  be
#read.   'Swt'  now  issues an error message indicating an illegal
#password and exits so that the user is never given a default  set
#of variables on a bad password.
