ERROR
DESCRIPTION
Gloo has a special 'error' variable that's not part of the normal
object heap. The error will be empty most of the time, but
if a command results in an error, this variable will hold the
error message until the next command is executed. The error
is a string and can be accessed by simply referring to the
path-name 'error'.
EXAMPLE
To see the last error:
> show error
To run a command that generates an error:
> put 3 into
'put' must include 'into' target
Then, showing the error
> show error
'put' must include 'into' target
But, as mentioned, the next command will clear out the last error.
If you need to keep track of the result of a command, you should
put the error into another object.
> create err as string
> put 3 into
> put error into err
