Re: string arrays

[Ansley Manke <ansley@xxxxxxxxxxxxx>]

Hello Hein,
Yes, starting with Ferret version 5.4 you can create a
string variable array.   Please see the entry "string variables, arrays"
in the index to the Users Guide:
http://ferret.pmel.noaa.gov/Ferret/Documentation/Users_Guide/current/fer_html.htm

For example:

yes? use coads_climatology
yes? let mnames = {"January", "February", "March"}
yes? repeat/L=1:3 (let mon = mnames[i=`L`]; plot/L=`L`/title=`mon` sst[x=0])

Note that the string variable is defined by default on an abstract
X axis, so if we tried to set the context X=0 for SST  using
PLOT/X=0, or SET REGION, Ferret would apply the X=0 to
the variable mnames as well, and not be able to loop through it.
One could also use TSEQUENCE to put the string on a time
axis, and then it's a bit simpler, as the L index applies to mnames
as well as sst:

yes? use coads_climatology
yes? let mnames = TSEQUENCE({"January", "February", "March"})
yes? repeat/L=1:3 (plot/L=`L`/X=0/title=`mnames` sst)
