[ferret_users] [Doubt in listing corresponding values a variable]



Dear Ferreters,
I have .nc data in which there are many variables  but only 2 dimensions that are l and m. l is time (l=1:365 ) and m is no events occurred (m=1:1753). so,  I want to list a variable by based on specific condition that is l=@loc:o
Example. variable called 'dist2land', so list/m=1:1753 dist2land[l=@loc:0], 
then I am getting list of 'dist2land' when it become 0 during entire l from 1 to 365 in each event from 1 to 1753. Now, I want to list the another variable called 'wind' corresponds to the list of 'dist2land'. 

How to list the variable corresponds to another variable being extracted on specific condition

Example:

I have data like this for each value of m(1:1753), L ranges from 1 to 365 shown below
L          dist2land        wind
1                  15                 50
2                  05                45  
3                   0                 15
4                   45                47
.                     .                      .
.                     .                       .
.                     .                       .
upto 365       25                  45


Now, I have list the data of dist2land and corresponding wind when dist2land value is 0.
i.e.  l=3, corresponding wind is 15. it should be done upto last value of m .i.e. 1753.

Thank you.
