[gradsusr] Cannot Locate Endwhile Statement Error

[Justin Hicks]

Jennifer,

How would I go about making the lat/lon values fixed? I know the aave
function needs 4 different lat/lon arguments. Would this just be 'd
ave(.......,lon=-179.5,lon=-179.5,lat=-89.5,lat=-89.5)'    or     'd
ave(.......,x=1,x=1,y=1,y=1)'?
