I'm assuming you are refering to drawing the line in GEMPAK.

You can use gpanot, such as:

 GDFILE   =  
 SATFIL   =  
 RADFIL   =  
 PROJ     = lcc
 GAREA    = uslcc
 PANEL    = 0
 DEVICE   = xw
 CLEAR    = n
 SHAPE    = line
 INFO     = 1
 LOCI     = #30;-115/40;-77
 LINE     = 5
 CTYPE    = c
 GEMPAK-GPANOT>

The above will draw a line from 30N 115W to 40N 77W.
