CHAPTER1.DOC = CHAPTER1.DOC[SIN-
The two options can be used together if you want to copy a piece of data from
the middle of a file.

13. Tab settings
",!h.'"
[Tn]
The tab settings on the copied file can be changed from those of the original
using this option. The number given by n puts tabs at columns n, 2n, 3n etc.
For instance, [T9] will give tabs at columns 9, 19, 29, 39 and so on. These set-
tings will be used wherever PIP comes across a TAB character in the file it is
copying. The TAB character is
I
CTRL
I -
rn
(ASCII code 9).
If
the word processor , or whatever created the text file, inserts spaces instead
of using the TAB character, this option will have no effect.

14. Transfer between user areas
h.!l@"
[Gn]
Normally it is not possible to use files from another user area. However, specify-
ing this option will allow transfer of files from user area n to the current area.

15. Truncate lines of data
",!h""
[Dn]
This option allows truncation of lines past column n, that is, PIP will delete
all characters between column n and the next carriage return.

16. Upper case conversion
h.nllM.
[U]
This works in the opposite sense to the [L] option in that it converts all lower
case characters to upper case.

17. Verify the copy
h,I"""
[V]
Verifying a file as it is copied acts as a double check on its integrity. When given
this option PIP compares the copy it has made with the original as it goes along,
ensuring a faithful reproduction containing only those errors that were in the
original.

18. Write to a read/only file
h.n@"
[W]
If
you have files which have been set to read-only using STAT, you can copy
over them if you give this option without the computer asking you if you want
the existing file erased and overwritten. As it is not possible to reverse the process
if you make a mistake, use with care!

19. Zero parity setting
h.ll@"
[Z]
The leftmost bit of a byte is usually the parity bit, and this option sets all these
high-order bits to zero. It results in converting 8-bit ASCII bytes to 7-bit AS-
CII bytes. It is as well to ensure none of the characters you are sending use
this bit because otherwise you could get some unexplained results. For example
graphics characters would be changed, and some console ESC codes would be
changed.
