Dear Vincent,

See the example in the User's Guide:

http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter3_Variables_and_Expressions.htm#_VPINDEXENTRY_483

Example: locating non-constant values

Determine the depth of maximum salinity.

yes? LET max_salt = salt[Z=@MAX]
yes? LET zero_at_max = salt - max_salt
yes? LET depth_of_max = zero_at_max[Z=@LOC:0]
