Re: [ferret_users] invalid command: grave accent doesnt evaluate to scalar

[Akshay Hegde <akshay.k.hegde@xxxxxxxxx>]

From the error message "invalid command: grave accent doesnt evaluate to scalar dep ge 50" its clear that dep is not scalar, The grave accent evaluation works only on a scalar.

For example

[akshay@localhost tmp]$ ferret
     NOAA/PMEL TMAP
     FERRET v6.93 
     Linux 2.6.32-504.el6.x86_64 64-bit - 11/13/14
     10-Feb-16 18:18    

yes? let array = {1, 2, 3, 4}
yes? say `array`
 **ERROR: invalid command: grave accent doesnt evaluate to scalar
          array
yes? let variable = 134445
yes? say `variable`
 !-> MESSAGE/CONTINUE 134445
134445

Hope now you can solve your problem
