+.th NEQN I 4/30/74
+.sh NAME
+neqn \*- typeset mathematics on terminal
+.sh SYNOPSIS
+.bd neqn
+[ file ] ...
+.sh DESCRIPTION
+.it Neqn
+is an nroff (I)
+preprocessor.
+The input language is the same as that of
+eqn (I).
+Normal usage is almost always
+.s3
+       neqn file ... | nroff
+.s3
+Output is meant for terminals with
+forward and reverse capabilities, such as
+the Model 37 teletype or GSI terminal.
+.s3
+If no arguments are specified,
+.it neqn
+reads the standard input,
+so it may be used as a filter.
+.sh "SEE ALSO"
+eqn (I), gsi (VI)
+.sh BUGS
+Because of some interactions with 
+.it nroff
+there may not always be enough space left before and after
+lines containing equations.

+.th NEWGRP I 4/8/75
+.sh NAME
+newgrp \*- log in to a new group
+.sh SYNOPSIS
+.bd newgrp
+group
+.sh DESCRIPTION
+.it Newgrp
+changes the group identification of its caller,
+analogously to
+.it login.
+The same person remains logged in,
+and the current directory is unchanged,
+but calculations of access permissions to files are
+performed with respect to the
+new group ID.
+.s3
+A password is demanded if the group has
+a password and the user himself does not.
+.s3
+When most users log in, they
+are members of the group named `other.'
+.sh FILES
+/etc/group, /etc/passwd

+nice \*- run a command at low priority
+.sh SYNOPSIS
+.bd nice

+command [ arguments ]
+.sh DESCRIPTION
+.it Nice
+executes
+.it command
+with low scheduling priority.
+If a numerical argument is given, that priority
+(in the range 1-20) is used;
+if not, priority 4 is used.
+.s3
+The super-user may run commands with
+priority higher than normal
+by using a negative priority,
+e.g. `\-\-10'.

+.th OD I 1/15/73
+.sh NAME
+od  \*-  octal dump
+.sh SYNOPSIS
+.bd od
+[
+.bd \*-abcdho
+] [ file ] [ [
+.bd +
+] offset[ \fB. \fR][ \fBb\fR ] ]
+.sh DESCRIPTION
+.it Od
+dumps
+.it file
+in
+one or more formats
+as
+selected by the first argument.
+If the first argument is missing
+.bd \*-o
+is default.
+The meanings of the format argument characters
+are:
+.s3
+.lp +3 3
+\fBa\fR        interprets words as PDP-11 instructions and
+dis-assembles the operation code.
+Unknown operation codes print as ???.
+.s3
+.lp +3 3
+\fBb\fR        interprets bytes in octal.
+.s3
+.lp +3 3
+\fBc\fR        interprets bytes in ascii.
+Unknown ascii characters are printed as \\?.
+.s3
+.lp +3 3
+\fBd\fR        interprets words in decimal.
+.s3
+.lp +3 3
+\fBh\fR        interprets words in hex.
+.s3
+.lp +3 3
+\fBo\fR        interprets words in octal.
+.s3
+.s3
+.i0
+The \fIfile\fR argument specifies which file is to be dumped.
+If no file argument is specified,
+the standard input is used.
+Thus
+.it od
+can be used as a filter.
+.s3
+The offset argument specifies the offset
+in the file where dumping is to commence.
+This argument is normally interpreted
+as octal bytes.
+If `\fB.\fR' is appended, the offset is interpreted in
+decimal.
+If `\fBb\fR' is appended, the offset is interpreted in blocks.
+(A block is 512 bytes.)
+If the file argument is omitted,
+the offset argument must be preceded by `\fB+\fR'.
+.s3
+Dumping continues until end-of-file.

+.th PFE I 11/1/73
+.sh NAME

+.sh SYNOPSIS
+.bd pfe
+.sh DESCRIPTION
+.it Pfe
+examines the floating point exception register and

+.sh "SEE ALSO"
+signal (II)
+.sh BUGS
+Since the system does not save the exception register
+in a core image file,

+refers to the last error encountered by anyone.
+Floating exceptions are therefore volatile.
