[ferret_users] Size of an array in a crooked case

[Olivier Marti <olivier.marti@xxxxxxxxxxxx>]

Hi,

I have defined a variable from a list of files : 

yes? list Liste_LMDZ
             VARIABLE : {SPAWN:"ls *_LMDZ_*.nc | sort -t '_' -k3 | sed 's/_LMDZ_..\.nc//'"   }
             SUBSET   : 25 points (X)
 1    /  1:"SISUTESW"
 2    /  2:"SIICECOV"
 3    /  3:"SIICTEMW"
 4    /  4:"SIICEALW"
 5    /  5:"CURRENTX"
 6    /  6:"CURRENTY"
 7    /  7:"CURRENTZ"
 8    /  8:"COTAUXXU"
 9    /  9:"COTAUYYU"
 10   / 10:"COTAUZZU"
 11   / 11:"COTAUXXV"
 12   / 12:"COTAUYYV"
 13   / 13:"COTAUZZV"
 14   / 14:"COWINDSP"
 15   / 15:"COTOTRAI"
 16   / 16:"COTOTSNO"
 17   / 17:"COTOTEVA"
 18   / 18:"COICEVAP"
 19   / 19:"COQSRMIX"
 20   / 20:"COQNSMIX"
 21   / 21:"COSHFICE"
 22   / 22:"CONSFICE"
 23   / 23:"CODFLXDT"
 24   / 24:"COCALVIN"
 25   / 25:"COLIQRUN"

Ferret seems to understand correctly the size of the array :

yes ? stat Liste_LMDZ

             {SPAWN:"ls *_LMDZ_*.nc | sort -t '_' -k3 | sed 's/_LMDZ_..\.nc//'"   }
             X: 0.5 to 25.5
             Y:  N/A
             Z:  N/A
             T:  N/A
             DATA SET: N/A
 Total # of strings: 25 (25*1*1*1)
 Maximum string length: 8

But not in all cases :

yes? say `Liste_LMDZ,return=isize`
 !-> MESSAGE/CONTINUE 2000
2000

How can I set a variable or a symbol to the actual size of the Liste_LMDZ array (the number of files). I need that to perform a repeat loop.

Thanks,

Olivier Marti
