Error handling by build-in IDL routines [message #14664]

Hi!

I have a question about error handling by build-in IDL routines.
Consider the following example:

fritz = 'the cat'
print, median(fritz)

IDL replies with:
% MEDIAN: Expression must be an array in this context: FRITZ.
% Execution halted at: $MAIN$

My question:
How does the function MEDIAN knows the name of the parameter (i.e.
FRITZ) I passed into it? How can I implement this functionality into my
own IDL routines?

Thanks for any suggestions,

Frank
