Thanks guys, the sed -n command is helpful.

Someone posted another reply, but it got deleted because I double-posted (notice the post is cut-off after "if." I can't remember what happened but I guess I ended up starting over and posted twice accidentally).

Here's jim mcnamara's reply to the deleted post, which got sent to my email:

Code:

awk ' {
     print "set time ", $1
     print "draw mark ", $2, $3
     } ' filename > file_for_a_graphing_program

output:

Code:
---------
set time 24may2003
draw mark -100.0 24.1
set time 25may2003
draw mark -100.1 24.0
set time 28may2003
draw mark -99.5 23.2
set time 05jun2003
draw mark -97.0 22.7
---------
source file = "filename" above:

Code:
---------
24may2003 -100.0 24.1
25may2003 -100.1 24.0
28may2003 -99.5 23.2
05jun2003 -97.0 22.7
---------

set_menu_mark

mark(3MENU)															       mark(3MENU)

NAME

       menu_mark - get and set the menu mark string

SYNOPSIS

       #include <menu.h>
       int set_menu_mark(MENU *menu, const char *mark);
       const char *menu_mark(const MENU *menu);

DESCRIPTION

       In order to make menu selections visible on older terminals without highlighting or color capability, the menu library marks selected items
       in a menu with a prefix string.

       The function set_menu_mark sets the mark string for the given menu.  Calling set_menu_mark with a null menu  item  will	abolish  the  mark
       string.	Note that changing the length of the mark string for a menu while the menu is posted is likely to produce unhelpful behavior.

       The default string is "-" (a dash). Calling set_menu_mark with a non-NULL menu argument will change this default.

       The function menu_mark returns the menu's mark string (or NULL if there is none).

RETURN VALUE

       The function menu_mark returns a pointer (which may be NULL).  It does not set errno.

       The function set_menu_mark may return the following error codes:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
	    Routine detected an incorrect or out-of-range argument.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

SEE ALSO

       ncurses(3NCURSES), menu(3MENU).

NOTES

       The header file <menu.h> automatically includes the header file <curses.h>.

PORTABILITY

       These routines emulate the System V menu library.  They were not supported on Version 7 or BSD versions.
