Re: [ferret_users] How can I check the variable

[Steve Guimond <guimond@xxxxxxxxxxxxx>]

Hello:
   If you would like to check whether or not a variable is defined in your
script, after you have defined a variable you could say:

let test = 20
say `test`

This will return the value of test to see if it is defined the way you
want.
