TXTA Cross sectional analysis using WINGRIDDS is very simple.  Several MACROS -
TXTB have been written to create Cross sections of various fields in this     -
TXTC Menu.  You will select your cross section here and may then analyze any  -
TXTD any field either from the WINGRIDDS command line or menu listing provided-
TXTE here.  If you use the menu selections provided in this section, a grid   -                                                                    
TXTF axis will be labeled.  If you create your own field, you must create your-
TXTG own grid axis by typing "XLBL." after the field is plotted.  Don't forget-
TXTH the period (.).

TXTJ To create the cross section axis, you will have to give the left (upper) -
