Replace based on an exact position
Trying to use sed - but having no luck.
I have a text file - I want to replace whatever character is in position 106, 157 and 237 w/ the string "xxx". Want this change for all lines w/in that text file.
I'm open to using awk or whatever command would be best for replacing characters based on the exact position. Seems like sed can do a lot, but for whatever reason, have had no luck figuring out how to replace on just position alone.
Thanks much!

XmTextFieldInsert(library call) XmTextFieldInsert(library call)
NAME
XmTextFieldInsert -- A TextField function that inserts a character string into a text string
SYNOPSIS
#include <Xm/TextF.h>
void XmTextFieldInsert(
Widget widget,
XmTextPosition position,
char * value);
DESCRIPTION
XmTextFieldInsert inserts a character string into the text string in the TextField widget. The character positions begin at 0 (zero) and
are numbered sequentially from the beginning of the text. For example, to insert a string after the fourth character, the position parame-
ter 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. If the XmNcursorPosition resource is greater than or is the
same value as position, the XmNmotionVerifyCallback is called.
widget Specifies the TextField widget ID
position Specifies the position in the text string where the character string is to be inserted
value Specifies the character string value to be added to the text widget
For a complete definition of TextField and its associated resources, see XmTextField(3).
