Re: [ferret_users] printing filename and line number at error

Hi,

While we're talking about debugging Ferret/PyFerret scripts, I'd like to point out some other commands and options that have been added in the last several years -- I know it can be hard to keep up with new things.

These are for digging into variable definitions:

SHOW VARIABLE/TREE lists out the variable definition and dependence on other variables (the alias for this is VTREE)

RETURN= keywords: RETURN=status, RETURN=isReady, and RETURN=defined

Hi—
 
When Ferret returns an error, is it possible to print the filename and
linenumber of the GO script?
 
I know how to print the filename.jnl ($0), but if it would be useful if
Ferret can tell me the name of the file and line number at any failure
of a command.
 
This is especially useful in my case where I am using jnl scripts that
call other jnl scripts and so on.
