NAME
newform - change the format of a text file
SYNOPSIS
newform [-an] [-bn] [-cchar] [-en] [-f] [-itabspec] [-ln]
[-otabspec] [-pn] [-s] [files]
DESCRIPTION
newform reads lines from the named files, or the standard
input if no input file is named, and reproduces the lines on
the standard output. Lines are reformatted in accordance
with command line options in effect.
Except for -s, command line options may appear in any order,
may be repeated, and may be intermingled with the optional
files. Command line options are processed in the order
specified. This means that option sequences like -e15 -l60
will yield results different from -l60 -e15. Options are
applied to all files on the command line.
-itabspec Input tab specification: expands tabs to spaces,
according to the tab specifications given.
tabspec recognizes all tab specification forms
described in tabs(1). In addition, tabspec may
be --, in which newform assumes that the tab
specification is to be found in the first line
read from the standard input (see fspec(4)). If
no tabspec is given, tabspec defaults to -8. A
tabspec of -0 expects no tabs; if any are found,
they are treated as -1.
-otabspec Output tab specification: replaces spaces by
tabs, according to the tab specifications given.
The tab specifications are the same as for
-itabspec. If no tabspec is given, tabspec
defaults to -8. A tabspec of -0 means that no
spaces will be converted to tabs on output.
-ln Set the effective line length to n characters.
If n is not entered, -l defaults to 72. The
default line length without the -l option is 80
characters. Note that tabs and backspaces are
considered to be one character (use -i to expand
tabs to spaces).
-bn Truncate n characters from the beginning of the
line when the line length is greater than the
effective line length (see -ln). Default is to
truncate the number of characters necessary to
obtain the effective line length. The default
value is used when -b with no n is used. This
option can be used to delete the sequence numbers

from a COBOL program as follows:
newform -l1 -b7 filename
The -l1 must be used to set the effective line
length shorter than any existing line in the file
so that the -b option is activated.
-en Same as -bn except that characters are truncated
from the end of the line.
-ck Change the prefix/append character to k. Default
character for k is a space.
-pn Prefix n characters (see -ck) to the beginning of
a line when the line length is less than the
effective line length. Default is to prefix the
number of characters necessary to obtain the
effective line length.
-an Same as -pn except characters are appended to the
end of a line.
-f Write the tab specification format line on the
standard output before any other lines are
output. The tab specification format line which
is printed will correspond to the format
specified in the last -o option. If no -o option
is specified, the line which is printed will
contain the default specification of -8.
-s Shears off leading characters on each line up to
the first tab and places up to 8 of the sheared
characters at the end of the line. If more than
8 characters (not counting the first tab) are
sheared, the eighth character is replaced by an *
and any characters to the right of it are
discarded. The first tab is always discarded.
An error message and program exit will occur if
this option is used on a file without a tab on
each line. The characters sheared off are saved
internally until all other options specified are
applied to that line. The characters are then
added at the end of the processed line.
For example, to convert a file with leading
digits, one or more tabs, and text on each line,
to a file beginning with the text, all tabs after
the first expanded to spaces, padded with spaces
out to column 72 (or truncated to column 72), and
the leading digits placed starting at column 73,

the command would be:
newform -s -i -l -a -e filename
DIAGNOSTICS
All diagnostics are fatal.
usage: ...
newform was called with a bad option.
not -s format
There was no tab on one line.
can't open file
Self explanatory.
internal line too long
A line exceeds 512 characters after being expanded in
the internal work buffer.
tabspec in error
A tab specification is incorrectly formatted, or
specified tab stops are not ascending.
tabspec indirection illegal
A tabspec read from a file (or standard input) may not
contain a tabspec referencing another file (or standard
input).
EXIT CODES
0 - normal execution
1 - for any error

BUGS
newform normally only keeps track of printable characters;
however, for the -i and -o options, newform will keep track
of backspaces in order to line up tabs in the appropriate
logical columns.
newform will not prompt the user if a tabspec is to be read
from the standard input (by use of -i- or -o-).
If the -f option is used, and the last -o option specified
was -o-, and was preceded by either a -o- or a -i-, the tab
specification format line will be incorrect.
