TXTA Cross sectional plots can be created very simply in WINGRIDDS.  By       -
TXTB executing this program, you have already entered the cross seciton       -
TXTC mode.  For additional MACROS designed to create specific cross sections, - 
TXTD procede to Menu <alt>-F4.                                                -
