Dear Guru's
I'm using Putty and want to edit a file. I know we generally use vi editor to do it. As I'm not good in using vi editor, I want to convert the vi into something like text pad. Is there any option in Putty to do the same ? Thanks for your response.

wcwidth
WCWIDTH(3) BSD Library Functions Manual WCWIDTH(3)NAME
wcwidth -- number of column positions of a wide-character code
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
int
wcwidth(wchar_t wc);
DESCRIPTION
The wcwidth() function determines the number of column positions required to display the wide character wc.
RETURN VALUES
The wcwidth() function returns 0 if the wc argument is a null wide character (L' '), -1 if wc is not printable, otherwise it returns the
number of column positions the character occupies.
EXAMPLES
This code fragment reads text from standard input and breaks lines that are more than 20 column positions wide, similar to the fold(1) util-
ity:
wint_t ch;
int column, w;
column = 0;
while ((ch = getwchar()) != WEOF) {
w = wcwidth(ch);
if (w > 0 && column + w >= 20) {
putwchar(L'
');
column = 0;
}
putwchar(ch);
if (ch == L'
')
column = 0;
else if (w > 0)
column += w;
}
SEE ALSO iswprint(3), wcswidth(3)STANDARDS
The wcwidth() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
