Insert Text on lines having the string word
I need help on how I can accomplish my task. I hope someone can help me since I've researching and trying to accomplish this for hours now. Basically, I need to comment-out (or insert a # sign in the beginning of the line) a line when the line has the specific word I am searching. Example I have this line:
Quote:
PM1SYSGFATRAGATEGFAGESDAFSOCAAGAAAGAG
ATAGATESETSOACGATATEGGPQMALDFJANMAGAG
LHAGNAGMLONAGLONLAGLQEEDAFGSTGXCGAGTA
OLAGULNUAGHALUDLNQPSOACNAGONLAONGAAGA
On line 2 & 4, the word SOAC (this is what I am searching for) appears, now I need the whole line be commented out just like below:
Quote:
PM1SYSGFATRAGATEGFAGESDAFSOCAAGAAAGAG
#ATAGATESETSOACGATATEGGPQMALDFJANMAGAG
LHAGNAGMLONAGLONLAGLQEEDAFGSTGXCGAGTA
#OLAGULNUAGHALUDLNQPSOACNAGONLAONGAAGA
then, I also need another code to reverse the effect, that is if the line has the word SOAC, it will remove the # sign at the beginning of the line. Thanks in advance for those who can help me!

xmtextreplace
XmTextReplace(library call) XmTextReplace(library call)
NAME
XmTextReplace -- A Text function that replaces part of a text string
SYNOPSIS
#include <Xm/Text.h>
void XmTextReplace(
Widget widget,
XmTextPosition from_pos,
XmTextPosition to_pos,
char * value);
DESCRIPTION
XmTextReplace replaces part of the text string in the Text widget. The character positions begin at 0 (zero) and are numbered sequentially
from the beginning of the text.
An example text replacement would be to replace the second and third characters in the text string. To accomplish this, the parameter
from_pos must be 1 and to_pos must be 3. To insert a string after the fourth character, both parameters, from_pos and to_pos, must be 4.
This routine calls the widget's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCall-
backWcs, or both. If both verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first
and the resulting data is passed to the XmNmodifyVerifyCallbackWcs callbacks. The XmNmotionVerifyCallback is generated if to_pos is less
than or equal to the cursor position and the length of value is not the same as the length of the text being replaced, or if the cursor
position is between from_pos and to_pos, and the distance from the cursor position to from_pos is greater than the length of value.
widget Specifies the Text widget ID
from_pos Specifies the start position of the text to be replaced
to_pos Specifies the end position of the text to be replaced
value Specifies the character string value to be added to the text widget
For a complete definition of Text and its associated resources, see XmText(3).
