Re: [ferret_users] Naming (sorting) output frames in the loop REPEAT/L=...

[Russell Fiedler <russell.fiedler@xxxxxxxx>]

Hi Sergui,

You want the embedded expression zero filled width feature

http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/variables-xpressions/EMBEDDED-XPRESSIONS#_VPID_183

something like

REPEAT/L=1,120,12 ( shade sst; frame/file=frame.`l,zw=4`.gif )             ! evaluate "L" padded to spaces with zeroes like fortran I4.4

should give you files like

frame.0001.gif

etc.

Cheers,
Russ
