Inserting n characters to beginning of line if match

I would like to insert n number of characters at the beginning of each line that starts with a given character. If possible, I would be most appreciative for a sed or awk solution.

Given the data below, I would like to be able to insert either 125 spaces or 125 "-" at the beginning of every line that begins with "@".

Code:
 
@PS001,001 VWB                 0   2 -1 -1 -1  5 -1   -1 -1  3  2     
@PS001,001 HJ==                0   7 -1 -1 -1 -1 -1   -1  3  1  2
 PS001,001 >CR=                0   2 -1 -1 -1  5 -1   -1 -1  3  2

Thank you so much.

DtEditorGoToLine(library call)											    DtEditorGoToLine(library call)

NAME
DtEditorGoToLine -- move the insert cursor for a DtEditor widget to a specified line SYNOPSIS
#include <Dt/Editor.h> void DtEditorGoToLine( Widget widget, int lineNumber); DESCRIPTION
The DtEditorGoToLine function moves the insert cursor for the DtEditor widget to the beginning of the line specified by the lineNumber argument. The cursor can be moved to the last line by specifying DtEDITOR_LAST_LINE as the line number. If the line is not currently on- screen, the contents for the DtEditor widget are scrolled to display the new insertion position. The lineNumber argument is the number of the line in the file, counting from 1. If the lineNumber argument is less than 1, the insert cur- sor is placed at the beginning of the first line. If the argument is greater than the total number of lines, the cursor is placed at the last line of text. The insert cursor can be moved to a specific character position with DtEditorSetInsertionPosition(3). The DtNtopCharacter resource can be used to control which line is displayed at the top of the DtEditor widget. The widget argument specifies the DtEditor widget ID. The lineNumber argument specifies the line number within the DtEditor widget. For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3). RETURN VALUE
The DtEditorGoToLine function returns no value. SEE ALSO
Dt/Editor.h - DtEditor(5), DtEditor(3), DtEditorSetInsertionPosition(3). DtEditorGoToLine(library call)
