TXTA All of the following MACROS have been set up for upper level data.        -
TXTB This menu contains MACROS for 300 mb data and other optional upper level  -
TXTC data for analysis at the forecaster's discretion.  For 300mb analyses,    -
TXTD you do not have to pre-set the level prior to running these routines.     -
TXTE Simply select from the 300 mb listings.  For other level/layer analysis,  -
TXTF (eg...400mb, 250mb, 200mb, etc.) set the level in the command line of     -
TXTG WINGRIDDS and proceed using the *** entries.  For example, if you wanted  -
TXTH to examine the 400 mb level wind and isotach field, exit the menu shell,  -
TXTI go to the WINGRIDDS command line, type: 400, return to the menu shell, and-
TXTJ select "L" and proceeding as usual. WINGRIDDS will remain at 400mb, or    -
TXTK the level of choice until it is changed manually (eg...changing the value -
TXTL at the WINGRIDDS command line) or a pre-set level macro is executed. You  -
TXTM can always note the level of your analysis from the header line above     -
TXTN each graphic in WINGRIDDS.                                                -
